Also, have you seen the Pandora Project?

My 770 is also very nice. In fact, its right up there with my ebookwise now that I think about it. I don't like the browser it uses, due to some limitations it has. The text resolution is pure win though. My guess is that browsing on this thing will be slightly better as far as rendering flash and stuff, except that unlike the 770, the lower resolution will not allow me to view a full web page as well as the 770 does.
I thought about one of those Airpanel or Viewpad's that you purchased. It seemed I would have similar issues as my DT-375 tablet so I wanted to try something more the size of my 770. It might have been wise just to purchase a Nokia 810. I guess we'll see.
