We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Sang-Jung, who is desperately in search of the perfect cordless critter to take some of the strain away from that trackpad.

"I'm heading to university next year, and I've purchased a MacBook. I'm also taking my four year old desktop, just in case I'm left with no computers when the MacBook is being repaired or whatnot. With only two USB ports on a MacBook, I want a Bluetooth mouse. Budget is about $100, and of course, it needs OS X support. Thanks for the help!"

Alright folks, it's time to get serious. Do you own a Bluetooth mouse that you can recommend? Recommend against? Be sure to spill your thoughts in comments below, and feel free to send in a question of your own to ask at engadget dawt com.

Here's what you get when a manufacturer tries to justify a $199 price tag on its newest headsets. The Jabra Go 6400 (pictured above) and Pro 9400 look to be standard noise-cancelling Bluetooth and DECT headsets, respectively, with a multifunction button to answer/reject/redial/mute calls and adjust the volume. However, these headsets are paired with an industry first touch-screen base for call management. The 2.4-inch capacitive LCD displays caller ID, call records, and lets users switch between their mobile, desk, and corporate softphones via a spin of the carousel. Fun sure, and exceedingly geeky, but hardly worth the $199 to duplicate functions already built-in to the headsets or accessible via the displays on the devices it connects to. Then again, these are aimed at office professionals (read: corporations) when they launch in September and $199 is nothing when you're spending someone else's money.

We've been playing with Motorola's recently-announced Endeavor HX1 for the past few hours, and we're just going to come right out with it: this is the best Bluetooth headset we've ever used. Moto claims that the HX1 is the world's first consumer headset to use "true bone conduction technology," a veiled (but obvious) reference to the external cheek-resting sensor found on Jawbone's devices -- and indeed, the Jawbone Prime is the most obvious direct competitor to the HX1. Both devices offer decent styling, feature optional earloops and a selection of earbuds for a tighter fit, are being positioned as premium headsets, and -- most importantly -- pack a ton of innovative circuitry all in the name of cutting noise in harsh surroundings. Head on over to Engadget Mobile for our quick take!

Sure VIZIO only just showed off new updates in its high end XVT series, but it's already planning the next generation of LCDs with VIZIO Internet Apps included. Packing widget functionality, 802.11n wireless networking and slider QWERTY Bluetooth remote, the SV422XVT, SV472XVT and VF552XVT Connected HDTVs are coming home in November, October and December, respectively. Already on deck to serve up content for your widgets are Vudu, Revision3, Facebook, Twitter, Rhapsody, Blockbuster OnDemand, Showtime, Flickr and more. The biggest surprise? There's apparently no price premium planned for these features, with the 55-inch clocking in at the same $2,199 price as the model it's replacing, though the 47-inch jumps $200 over the previous edition to $1,699, while adding the local dimming LED backlit technology previously reserved for the 55-inch. The 42-inch will be the first and cheapest available at $1,199 (sans LED) -- we'll see if that bar is low enough to get viewers to jump into the internet-connected display future.

To think, we've been waiting on the edge of our seats since January to get our hands on Ecamm's BT-1 wireless, Bluetooth-enabled webcam for OS X. Sure, 640 x 480 / 15fps H.264 video quality is comparable to what our MacBooks get anyway, but hey, at least you can be a little more artsy on your Skype calls without losing that prime display viewing angle. All that waiting doesn't matter now, anyway, since it's finally shipping out. Price is $150 and it includes a mini-tripod and USB charger cable -- can't seem to get rid of wires entirely just yet. As for Windows support, it's still not there officially, but we've no doubt some intrepid young coder with an afternoon to spare will fix that.

Motorola isn't shying away from a fight here with its Endeavor HX1 Bluetooth headset -- and if there's anything the Bluetooth headset industry needs, it's some manner of controversy. The company is calling its new HX1 the "only Bluetooth headset to use true bone conduction technology," with a user activated "Stealth Mode" that switches the set from regular mic to an in-ear sensor which picks vibrations right off the bone for talking in particularly noisy environments. Jawbone, on the other hand, picks up vibrations from the outside of the face, but primarily as an "Activity Sensor," though the latest version nabs some audio from those vibrations -- both manufacturers naturally claim a military heritage to their technology. It'll take some actual testing to see who wins out, but it sounds like some good tech from Moto all the same. We do know one thing, however: no amount of in-ear stylings can ever ease your transition into general society. No word on price of a US release date for the HX1, it hits Asia in July.

We can't say for sure, but we've all ideas that Broadcom has spent the majority of the past month just rolling in dough that's being begrudgingly transferred in from Qualcomm. During the downtime from that, however, it apparently whipped up three new Bluetooth 3.0 + WiFi modules designed to bring both connectivity options to netbooks and UMPCs that would otherwise go without. Said cards arrive in half mini-card form, which ought to slide into places where only one or the other used to fit. We're told that the company is now sampling these very chips, with volume production expected to begin in Q3 2009.

Man, talk about a long time coming. The last time we saw a line of i:Virt watches from Citizen, it was a bright fall day in 2007, and obviously our style threshold was entirely different. Thankfully, the outfit's latest line of Bluetooth-enabled timepieces are far sexier, though we have to say -- the fact that they only support Softbank phones makes us shed a tear on the inside. As with most other BT watches, these too will display emails, alert you of incoming calls and even clue you in on the latest news (via RSS, we suspect). Both the TM84-0341V and TM84-0342V feature a stainless steel case and a life of around five days with a full charge; there's no mention of price, but frankly, we're too depressed to even find one. Poor us.
