I've slowly gotten my mom used to the iPhone to a point where she is comfortable with it. I want to get her an iPad 4 as her first tablet. She is not a power user by any stretch of the imagination and will probably only use 5-10 apps a most for video chatting, Facebook etc. So is the iPad 4 for sufficient for her use case where she can use it for a few years? Are the internals sufficiently future proof? I am thinking the iPad 4 and not the Air for two reasons: (1) $100 cheaper, (2) Larger bezels to hold the iPad which probably makes it easier to operate for a first time tablet user. Thoughts?
