Hi - new to this Board and also about to take the plunge and purchase my 1st Ipad. First question - do I go for the Ipad 3 16gb or an Ipad 2 32gb? I will use it for reading books, surfing the net, calendar and newspapers and my son will no doubt want lots of games and educational stuff/games. Here's the really daft question - once I download an app that I like, do I then need to have internet access (wifi) everytime I want to use the app? If I want to watch a film, do I again need to have a wifi connection, or can I request/download the film and then watch it without wifi? Thanks.
