Most people who read email actually like to write it too. An on-screen keyboard just doesn't cut it, and plus, the screen stays "up" on it's own, no need to be held and then when you're finished you can close it all up to protect the screen. I'm not sure anyone has actually imagined sat on the sofa with this thing, wrist aching from holding it and compensating for key presses. Awful invention, if it had come with the "oh so maligned these days" stylus it might have had some utility.
