Um, (drooling) I want!

Sweet, I'll throw my name in the hat.

No, if you read about the real world experiences of people who've installed e-bike conversion kits you'll see that the lead acid battery packs have a life span of about 3 years, if cared for properly. LION can't match that. (Guess what technology is used for deep cycle batteries in RVs--lead acid.)

I like pink!

There are literally dozens of hub motors available for electric bike conversions now. The problem is battery life and price. Truthfully, all the kits use cheap Chinese hub motors, but the mark up can vary dramatically. Battery technology is the other draw back--if your round trip mileage is more than 14-20 miles, you'll need to augment with pedaling because most of the batteries (especially the packs using lithium ion batteries) won't last that long.

There are also some safety issues--if you have an aluminum fork or a mountain bike with springs on the front fork, you cannot safely mount a hub motor on the front wheel. You'll need to mount it on the back wheel. (That's my predicament--I'd love to put a hub motor on my mountain bike, but it will have to be mounted on the rear wheel. I may break down and buy one this year.)

Here's a link to a web site with a video that shows how fast you can go--I'm tempted to buy from this site since he has reasonable prices. http://ampedbikes.com/

The Mio community has a number of members who have developed hacks to unlock many of the units and turn them into PDAs and multi-purpose GPS units. I have unlocked my unit, which I use as a PDA; I also run OziExplorer for topo maps and other off road maps when I hike and bike. I love my Mio; I use an external battery and run it all day. It has a bright, wonderful 4.3" touch screen and can accept 16 GB SDHC cards. Here's a screen shot showing media player running.

Oh, my aching hand would love this.

Typical MS, they're behind the curve, still. I don't see this being a viable enterprise. Software won't be a big attraction to draw consumers to one of their "branded" stores and they won't provide much discount (if any) for their gaming equipment or Zunes. I never expect to see them get close to selling at Walmart's prices. Shows how desperate they are to stay relevant. (Linux must be making more inroads than I thought in the personal computer business.)

I can if you begin using it for regulatory enforcement in the US. Especially, as more onerous environmental regulations get enacted, watch technology like this be used for surveillance of individuals, not just companies. Get caught using an older, "dirty" gasoline powered mower as the thing passes overhead, get a letter imposing a fine the next week (too many infractions well something more serious may happen). (Should you think that the example of the gasoline powered mower is an exaggeration, new EPA regs mandate new standards for all gasoline powered equipment. The question is how many iterations of the regulation will be promulgated before criminal penalties attach to individual use of non-compliant equipment. At present, companies will be compelled to use compliant equipment, but it's simply a matter of time before consumers will, too.) The possible uses domestically are endless. Orwell's prediction, although off by a few decades, is coming to fruition, unfortunately. Technology isn't really our friend.

Licenses tags or tires too, if states like Oregon have their way. (You do realize that RFID tags have been placed in new tires in the US for almost 8 years now, thanks to the US Congress.) Oregon is upset by falling gasoline sales (which means decreased gas tax revenue). They're on the verge of mandating GPS in everyone's vehicle and imposing an annual "milage" tax based upon how many miles you've driven--they even want to tax out-of-state residents who drive anywhere on their roads. (Don't expect to see them abolish the gas tax if they actually impose this new tax. I suspect the new tax will simply be additional revenue.) I can see a new federal travel tax (and not just based on travel by auto--why not get walking, flying, sailing, biking? Heck, all 50 states might impose their own state travel tax. Ain't technology grand.
