It has all the features I want and need, I don't mind (although also don't particular care for) WM, and it looks absolutely perfect, except for one crucial problem. It only has a 2.8" screen. My current PDA (a Palm OS Sony Clie) has a 3.5" screen, and that's as small as I ever plan to go. Reading GPS maps on a 2.8" screen sounds both unpleasant and nearly useless. I have a friend with an HTC TYTN, it also has a 2.8" screen, and it's also simply too small for useful web browsing.

If it had a 3.5" or larger screen, it would be absolutely perfect. As it is, I'm wating to see what is announced at CES and MacWorld in January. If something with a 3.5"-5" screen and either a qwerty keyboard or a multitouch virtual keyboard, wifi, and GPS comes out, then I'll decide between it and the n810, otherwise I'm getting an n810. I'd like a real camera, I'd like something that would work as a phone, but the tiny screen is just too tiny for me.
