My physical therapist says she uses her mainly to contact back and forth with her kids. Yeah, you can use a cell phone, so I'm not sure what she means by that.That tiny tiny screen just does not impress me one little bit. A tiny computer that can tell you the time, or let you read this forum two words at a time? Come on! They sell them to the terminally niave. IMHO
Maybe it has features that make such an interaction easier? Mostly, I agree that the screen is too small for anything useful online.
