my friend uses an ipad for her job and its critical. she is an insurance assessor. goes all over the city and uses the tablet to record things. in this situation:
phone size = too small
laptop = too clumsy.
thats just one example of a tablet computer in its element. another is for students. i'd much rather have a device that doesnt take up screw all room in my back pack than a netbook. you need something with an ARM cpu that can suspend/resume instantly, weighs next to nothing, and is wide enough to be like a sheet of paper. hell, if used with a stylus it would be perfect.
