While logging into T-Mobile’s site the other day, I noticed the new T-Mobile MDA. Looks like a possible Sidekick competitor to me. Features include:

• Windows mobile.
• Instant messaging (Yahoo!, MSN, and AIM).
• QWERTY keyboard.
• EDGE (Enhanced Data rates for GSM Evolution).
• 1.3 megapixel camera.
• Bluetooth.
• SD expansion.

If you’re into Windows products, this looks like a pretty compelling device. I’m completely addicted to messaging features (IM clients and QWERTY keyboards), which the MDA seems to have covered, and I’d love to have EDGE and a decent camera — both conspicuously missing from the Sidekick 2. I wouldn’t mind Bluetooth, either, though I steadfastly maintain that the Sidekick 2 actually negates the need for Bluetooth (the only thing you need Bluetooth for on the Sidekick 2 is a headset, although since I use mine much more for messaging and personal information management than for voice calls, a Bluetooth headset doesn’t buy me much more than just another rapidly depreciating device to try to keep charged).

To be fair, you’d probably want to compare the MDA to the Sidekick 3 rather than the Sidekick 2. Of course, the Sidekick 3 has yet to be released, and there is still no official information available, but according to rumors, it looks like EDGE, SD, and video are all in the works. And I’d be shocked if it didn’t have a significantly better camera than the Sidekick 2. At the end of the day, though, there are all the other things I love about the Sidekick which the MDA just can’t touch.

Microsoft fans might be wise to wait for Project Origami before purchasing their next device. Right now, Origami seems to be a code name for a lot of clip art and technical melodrama, but I suspect it will materialize into something that will compete with the new OQO Tablet. Or if you live anywhere else in the entire world except the United States, keep an eye out for the new Sony Ericsson P990 hand-held powerhouse, proving once again that the US has become the mobile third world.
