Last week's Switched On explained how Dash Navigation's use of wireless technology intends to teach the GPS bloodhound some new tricks, but the company plans to primarily use its new design to tackle two of the hottest trends in portable navigation. Many GPS units now offer real-time traffic information based only on incident reporting, and the devices are not very intelligent about weighing the traffic in alternative routes to determine the fastest path. As a result, you could drive off of the freeway and into the fire. In contrast, Dash's traffic esimates are based on traffic flow. It begins with a historical database of what traffic speeds are like for sections of highways at specific times of the day.

Beyond that, Dash GPS units act as probes, reporting back on actual speed of cars on those segments. This clues in those who come after them about construction and other aberrations from traffic patterns. To do this effectively, though, Dash must take advantage of a network effect; the company estimates that a few thousand Dash units should provide good coverage of major roadways within large cities.

While the Dash unit includes a point of interest database, it can use its connectivity to query a local search engine such as those offered by Yahoo! and Google, leveraging the efficient if fallible semantic categorizations that these Web-based local search engines offer. Typing in practically any word will return listings, even if they are not in the title of the business. For example, typing "burrito" might return local Mexican restaurants that have them on the menu. Dash is also exploring RSS feeds -- a natural fit for this kind of device -- as well as enhanced business listings that might include, for example, hours of operation.

No one would ever accuse the Dash team of low self-esteem. "What the TV did for entertainment and the cell phone did for communication, Dash will do for driving." the company's Web site crows, A more accurate analogy for Dash, though, would be what TiVo did for television, that is, give consumers a greater degree of control over the media or information they're trying to manage in a contextually relevant way.

Dash plans to achieve its five-star impact rating via a portable GPS device. The portable GPS market shifted into high gear a few years ago when Magellan offered a hard disk inside of its Roadmate 700 units. Consumers no longer had to deal with cumbersome PC downloads; street-level maps of the whole country could be pre-loaded. A year later, a gigabyte or two of flash memory is enough to include street-level maps for the United States. Magellan representatives recently noted that it plans to switch completely from hard drives to flash in the next generation. The TomTom Go 910 can even hold maps of the U.S. and Europe for those leisurely drives across the Atlantic Ocean.

Earlier this week, Napster noted that it had hired UBS Investment Bank to explore options for the company, including a sale. The move falls in line with a comment from CEO Chris Gorog at its last earnings call that the company's management team did not have their "heads in the sand" regarding a possible acquisition.

They'd also likely want to reassure investors that their heads are not in the clouds or in the stars. However, the reasons are as clear as CD-qualtity music for having their heads somewhere between those two celestial entities -- around the orbit of two geostationary satellites called Rock and Roll that that deliver the XM satellite radio service. The partnership between XM and Napster, which turned a year old in July, has demonstrated why XM would be a suitable white knight to snap up the former pirate haven.

Napster would help XM on the path toward becoming a radio business, not a satellite radio business. Both XM and Sirius offer Internet-based streaming today and Sirius channels are available to Sprint cellular subscribers while XM's are available to Alltell customers. Indeed, both XM and Sirius must recoup the expense involved in operating satellites, but there are many examples of media companies that started out tied to specific technologies, among them AOL's software and HBO's early set-top boxes.

Consider companies with an affinity for cubes that offer digital audio players and you'll probably think of Apple -- progenitor of the G4 Cube and the large glass one crowning its Fifth Avenue store -- or perhaps the developers of the MobiBlu player, once the "world's smallest" that was sold exclusively at Wal-Mart for a time. But specialty retailer Brookstone also has an MP3 device that embraces the six-sided solid. Hanging it around one's neck, though, would be a feat even for Flavor Flav.

While many products exist that enable you to stream music from your PC to a stereo in another room, or to act as docking speakers for the iPod, the SongCube is one of the few shelf systems on the market that includes its own hard disk for storing music -- no tenuous streaming or PC required. Other products in this exclusive club include the aging JVC NXHD10 executive microsystem, which includes only a 10 GB drive, and Sony's NetJuke line, available only in Japan.

The SongCube's main unit is about as tall as an iPod Hi-Fi (sans iPod) and about the third of the width of one, although it's about 25 percent deeper than Apple's iPod speaker accessory -- quite compact at first glance but not, geometrically strictly, a cube. Its speakers are also unobtrusive and Brookstone even bundles speaker stands with the system. However, there's a catch. The SongCube requires the use of its floor-standing 50-watt powered subwoofer where the main power switch is located. Normally, this wouldn't be much of a drawback. However, it comes into play when loading music onto the device, as I'll discuss shortly.

In July, I discussed the confusion that results when carriers disable Bluetooth capabilities, specifically OBEX and DUN, which were not the names of two New York City detectives on the '70s comedy Barney Miller. The column proposed that the Bluetooth Special Internet Group (SIG) step up efforts to ensure that a Bluetooth device is capable of what a consumer would expect it to do, and thus apply marketing pressure to the carriers.

That column led to a discussion with Mike Foley, executive director of the Bluetooth SIG, who noted the range of capabilities that Bluetooth has acquired. For example, relatively few consumers are aware that their Bluetooth devices can print using the wireless technology or can stream stereo music using the A2DP profile. As a result, in June the SIG developed a set of five "experience icons" that cover five Bluetooth-enabled tasks -- printing, input, headset, transfer and music.

Among the most useful in terms of carrier tampering will be file transfer, which has been blocked in the past. There's no icon for dial-up networking yet, though. According to Foley, there is still more work to do on simplifying the use of a cell phone as an untethered modem.

In their 1997 song Tubthumping, Chumbawumba sang, "I get knocked down but I get up again," describing well the daily cycle of sleep and awakening. For many of us, that cycle renews with the aid of a nightstand staple now targeted by Chumby, likely not named after the one-hit wonders. Depicting a clock radio on their Web site, Chumby's developers ask, "Um, this is the Internet era, isn't it? Why is this still sitting next to my bed?" The answer is that primarily there haven't been many alternatives until now, but also because alarm clocks are cheap and have easily understood and compelling functionality.

That is not yet true for Chumby, a broadband beanbag for Flash developers that promises a flexible feature list and exterior. According to Christine.net, Chumby has a 266 MHz ARM controller, 32MB of SDRAM, a 3.5-inch LCD with LED backlighting, stereo speakers, a headphone jack, and an ambient light sensor. It runs Flash Lite 2 (roughly equivalent to the functionality of Flash 7), and has a USB port and a squeeze sensor. Chumby looks a bit like a soft-shell TomTom Go, and its casing can be personalized, BeDazzled, encrusted with Swarovski crystals or even replaced entirely with what could be -- if it ever reaches iPod-like popularity -- an ecosystem of enclosures.

Watch maker Fossil was among the first companies to support MSN Direct, the smart objects technology first offered by Microsoft in a number of timepieces. Earlier this year, the company, through its Abacus brand, revisited the technology in its Abacus Smart Watch 2006.

While the watch is still on the bulky side, it's slimmed down a bit and Fossil has used a sloping profile to minimize the watch's girth. In fact, the Abacus 2006 was no thicker than a workaday Seiko men's watch I purchased last year. Other improvements include more memory and the inclusion of a year of MSN Direct service. Abacus offers the watch with a metal band that nicely complements the watch's masculine design for $179, as well as a number of leather straps. Unlike nearly any other consumer product that includes Microsoft software, it has nary a trace of Microsoft branding.

Like all of the MSN Direct watches, the 2006 Abacus uses FM radio technology to communicate updates to the device. After activating the timepiece, you choose content channels from a Microsoft Web site. The content has diversified considerably from when the watch was first launched, but it's still mostly focused on the basics, including a variety of different "faces" -- two of which I found attractive, three more of which were acceptable, and several of which were just hideous.

In January, I wrote about my experience with PC Mover from Laplink Software, an effective solution for migrating your applications from one Windows PC to another, even (with some caveats) when those computers are running different versions of Windows. But there is another kind of migration that PC users often face, upgrading their hard drive. Unfortunately, backup applications that rely exclusively on file-based backup can't restore a working Windows installation because they don't capture what is known as the master boot record. (Apple, incidentally, notes that Time Machine, which creates browsable, file-based backups, can be used to restore or migrate to another Mac, but that Time Machine archives themselves are not bootable.)

So, in recently upgrading a PC hard disk, I tried Acronis True Image 9, a utility that can create an "image" or exact copy of one's hard drive as well as file-level backup. TrueImage automates much of the hard disk migration process, even expanding the partition on the target drive to its maximum so that your new drive is ready to go after reinstalling.

At this week's World Wide Developers' Conference, Apple nary missed an opportunity to jest at how certain features in Vista bear similarity to those in Mac OS 10.4, recalling banners from the 2004 geek gathering enjoining the developers of Windows to "start their photocopiers." However, the copy machines at Microsoft aren't the only ones free of cobwebs. For example, a decade before Spotlight shone in Tiger, utilities such as On Locaiton provided classic Mac OS lightning-fast index-based searches. And Konfabulator, now owned by Yahoo, inspired Dashboard.

Spaces, slated for Leopard, promises to be merely the best-implemented in a long line of virtual desktops long known to Unix users and even made available as a PowerToy from those Windows wannabes. And what of Time Machine, the fourth-dimensional feature that was the WWDC showstopper? Among its predecessors are System Restore, a drably named subset of Time Machine's functionality available since Windows ME; Rewind, a classic Mac OS utility once promised for Mac OS X; and GoBack, a PC utility that was purchased by Symantec. When I first saw GoBack, the earliest of these, which debuted at a DEMO conference, I thought it was one of the most ingenious pieces of software I'd ever seen -- even without Time Machine's extraterrestrial eye candy.

At Microsoft, we know that customers appreciate the importance of choice and compatibility. If you're in the market for a new digital media player, look for the logo that ensures interoperability with a wide variety of players from our valued partners and wretched competitors such as Creative, Samsung, iRiver, Archos and Sandisk. PlaysForSure means that you won't be locked into one company's digital media player. On the other hand, isn't that worth the convenience and elegant integration you'd get with a sweet, sweet Zune player?

PlaysForSure also means that you'll have access to the widest variety of digital music stores, so you can choose from content offered by Napster and Yahoo! Music or, for an even better experience, you can take advantage of the great integration of MTV Networks' Urge with Windows Media Player 11 -- an experience so good that we'd just as soon pass on it in favor of a whole new music management application that will integrate with our own player and store. Finally, we'll have something to compete with that company that owns MSN Music. There are also a number of excellent PlaysForSure video services such as CinemaNow and MovieLink that we're going to trounce with the service supporting Zune.

With all the recent coverage surrounding Microsoft's rumored portable music player Zune, some may conclude that Engadget's editors have highly active and detailed imaginations and exceptional Photoshop skills that they employ without hesitation in the traditionally slow summer tech news months. Others, however, may be convinced that Microsoft is following through on Steve Jobs' prediction that the company will enter the market with its own branded player. The pictures of the Zune hardware show an attractive but not groundbreaking design, one that looks similar to a Gigabeat with a small wheel replacing its crosshairs, or a Sansa e200 with its wheel shrunk and a few extra buttons.

Much of the discussion around Zune has focused on the strategy shift it would mean for the software giant and the competition that it would bring to Microsoft's current hardware partners. But the company's continuous user interface refinement of Windows Mobile and expecially its deep pockets can let it fight the iPod in ways that its current partners simply can't. Microsoft could best leverage its war chest via player subsidization, accessories and advertising.

Regarding player subsidization, if the Xbox consoles have been any precedent, it's doubtful that Microsoft would lowball its player's pricing too much. The company would likely rather bring out a full-featured device that wins the hearts of early adopters. However, it could subsidize expensive advanced features that may be a bit ahead of the market. The rumored inclusion of WiFi would enable Microsoft to play upon one of the benefits of subscription services – legal peer-to-peer music sharing among devices of licensed content -- and allow a tighter level of integration with the Xbox 360. This could also drive a viral marketing effect. Indeed, Microsoft, more than any of its hardware partners, can justify subsidization because it could be considered investment in the future of the Windows Media licensing ecosystem – an interest in which its current partners are only tangentially vested -- or the broader digital lifestyle campaign if Micrsoft eschews Playsforsure as rumored.

"Hey there. Is this place new? I've been to this mall many times and never saw it before."

"Yes, sir. Welcome to The Hewlepsmark Inkjet Printer Cartridge Experience."

"No kidding. A whole location devoted to just to printer cartridges?"

"Not just any printer cartridges. Only Hewlepsmark inkjet printers. You see, after some failed early experiences with tech manufacturer-direct stores from Gateway and Microsoft, the past few years have seen Apple, Sony, Nokia, Palm, Nintendo, and now Pioneer move forward with their own retail stores. Even Dell and Samsung are using their own retail space to showcase their products. Soon we're bound to see Coby Corner, Craighead, and jWINdow Shopping. It's all the rage.

"So, we thought, as one of the world's premiere printing companies, why not develop an environment where we can really reinforce the brand identity and provide a showcase for our great variety of inkjet colors, the best printer cartridge shopping experience possible. We also have weekly seminars, like the one next Wednesday about the link between third-party refill kits and gingivitis."

Last week's Switched On discussed how Microsoft would go about creating a next-generation PC, but such a leap forward would likely have to be consumer-focused and incompatible with Windows. Why would Microsoft create a new computing platform aimed at the same usage scenarios as today's PCs?

First, there's a market. Nowadays, we have very high PC penetration in the US, and the kind of advanced technological showcase I'm considering wouldn't be suitable for developing countries like the One Laptop Per Child project, but surely there are enough early adopters who would flock to the state of the art for a PC that offered as radical a break with the past as the Mac did in 1984 -- even as a second PC.

Second, creating a new consumer platform would help alleviate outcries from Microsoft's existing hardware partners. Much of HP's and certainly Dell's bread is buttered by business users. Windows -- or at least its user interface conventions -- "work" for many of the productivity tasks that businesses need. In any case, there is tremendous infrastructure around them. Businesses are also slow to adopt new versions of Windows, much less a new paradigm of computing. However, some verticals can won over sometimes, the way Apple rose to dominate the publishing business (or at least the art and layout portions of it) once upon a time.

Each week Ross Rubin contributes Switched On, a column about the future of technology, multimedia, and digital entertainment:

The Xbox 360 is already considered by some to be the best product that Microsoft has ever produced. That's not surprising as it's been among the few where the software giant has controlled "the whole widget" -- choosing the processor, designing the hardware, and developing not only the operating system and user interface, but a host of licensing standards, services and infrastructure supporting Xbox Live.

In short, with the Xbox 360, Microsoft has proven that it can play the architect, succeeding at the vertical integration game that Apple has traditionally nailed with the Macintosh and iPod. Microsoft hasn't reached market share dominance with the Xbox 360 as Apple has with the iPod, but on the other hand the Mac market – while profitable for Apple -- still has a small share of the PC marketplace despite its integration advantages.

If Microsoft can succeed at producing its own videogame hardware and is widely rumored to be working on its own branded portable media player, could it succeed at, say, its own PC hardware -- that is, going beyond the keyboards and mice that it sells very successfully today? To do so, Microsoft would have to produce a personal computer that broke with today's GUI conventions and Windows application compatibility.
