For iPhone.

I use this thing all the gosh darn time - internet, e-mail, music, gps, weather, notes . . . and occasionally as a phone.  The only thing my old Pocket PC did better was have a pull out keyboard, and copy and paste.

One down, one to go.

I await a reconfigurable tactile display that lets me have a keyboard when I want and a large, smooth screen when I don't.  Also handy for the blind, I would think.
