Not sure what to call it -- supersized phone or mini pad... but the upcoming Dell Streak seems to be just the thing I need for my travels!?!
It's sized between an iPhone and iPad. Assuming the screen is big enough, this can serve as a reader, music/video player, camera, video, browser, communicator -- and light to moderate PC duty as well.
I might even buy one -- when 2.0 comes out. :)
