The 800 has a brighter and sharper screen [my 770 always looked like very slightly frosted glass], runs faster, and seems to have less tendency to get confused with multiple applications running as compared to my 770. On the other hand, to me, the hand-feel of the 770 is way better than the 800. To me, the 'lump' along the top edge of the 800 just doesn't feel right. The 770 felt like a gadget from the future, while the 800 feels like just another pda, with its sliver trim and hard to push buttons on the top just making it feel even more cheap compared to the 770.

While I am using the 800 [for speed and multi-application reliability] nearly 100%, I don't know that I would have stepped away from the 770 had it not been for the closing-compusa pricing on the 800.

In the best of all worlds, I woulld have been much happier if they kept the physical design of the 770 and just upgraded the screen, processor, and went to full size SD memory. I don't even see where the two speakers of the 800 are an upgrade, given the spacing involved.

Just my two cents.
