RIM working on Bluetooth watch, other spellbinding accessories?

We're not sure why we didn't hear more about this way back at RIM's WES conference way back in May, but it was apparently mentioned by VP Antoine Boucher at the time that they're working on a Bluetooth-enabled watch. Furthermore, it's said to be more advanced than the models Sony Ericsson has put forth so far, featuring streaming audio (3.5mm jack on the watch, perhaps?) and Twitter / Facebook updates in addition to the usual things like caller ID and text messages. Note that the image floating around today of this thing isn't real -- it's just a ony Ericsson MBW-100 with a swapped logo -- so it remains to be seen what this magical wrist accessory will look like, assuming it's real and coming to retail. It seems Boucher also mentioned a high-end Bluetooth headset codenamed "Alpha 1" that'll allow you to stream music and get navigation directions through some sort of totally awesome silicone earpiece boasted to possibly be "the best solution on the market." It's pretty hard to pique a lot of interest these days with something as vanilla and ubiquitous as a headset, but at any rate, it's interesting to see the depth of RIM's apparent commitment to the accessory market right now.

'Sources' say no Apple tablet until 2010

And so it continues. It seems like just when rumorland is ready to claim this month or this season as the absolute certain suretime of the Apple tablet, those pesky "sources" get cold feed and bump the imaginary release date back a year or so. At least that's what the folks at The Loop are saying. They claim "very reliable sources" have called the September rumor "flat out wrong," and state that we won't see the tablet until the first half of next year sometime. Sigh. Don't give up internet, if we just wish hard enough we know that anything is possible.
