Adding a keyboard would make me actually consider getting one. You may be perfectly happy without one, but I want buttons.
And I don't think I'm alone in this feeling. Also, giving it a keyboard would further differentiate it from the iTouch.
I actually love the touch keyboard. Saves a lot of space and it guesses what I'm typing rather well. You gotta try it out for a week.
