Built-in EVDO sounds cool. As long as the EVDO access is very reasonably priced, like somekind of very affordable per MB cost with no monthly payment or something like that.
I wish the wireless was HSDPA and compatible with wireless data around the world, even built-in WiFi would have been nice.
As it loads New York Times and Washington Post every morning, it should also be able to load ones Google Reader feeds in the morning.
Touch-screen and smart keyboard will be awesome. There should be somekind of browser in there.
The Electronic Books should be sold for very reasonable prices, since so many intermediaries including the printing of the paper back version are skipped. There should also be somekind of way to let people get the taste of a book for free before buying, something like a few chapters should be free, and payment is confirmed at that point.
Getting access to Google apps on e-paper will be awesome. Such things as search, blog search, Google maps, Gmail, Google News, all that should be working over the EVDO, using Google Gears to speed up the process and provide offline functionality to save battery power.
Taking notes with a foldable USB keyboard, and thus post to blogs, emails, reviews and more directly using the device, without the need to have a computer.
