Interesting. My PRS-T1 is a really nice device. Once you've got your files on, it's great. The screen is nice, the multi-touch is bloody useful, if understandably laggy, it weighs almost nothing, and being able to hack the underlying Android and install Kindle reader is both awesome and hilarious. The one component it's really missing is an accelerometer for automatic screen rotation, but that's no big deal. If you're leaning toward a Kindle but don't want to be sandboxed, the T1 lets you do both (after some easy modding), and I love it for that.
Getting your files on is the problem, though. It's a great device with really irritating desktop software (there's a shocker). If you connect it as a straight mass storage device and copy stuff that way, it's fine, but the limited on-device controls leave you without a way to correct file titles, and creating collections on the device is a bit more laborious. And god forbid you create a collection using one desktop, then try to sync it with another one. You end up with collections that cannot be deleted. Genius.
If the T2 has an accelerometer and software that's not utter shit (and they don't lie about the store being available at launch, then make customers wait months for it) then it'd be superb.
