I am considering upgrading my iPad. I currently have a 16gb 3rd gen and I use it mostly for Web, reading magazines, forums, light gaming and some basic apps. I am looking at the mini as I really love the former factor but the retina part kind of bothers me. I am also looking at 4th gen but just not sure I need that power yet and since it seems apple is now on a 6 month product cycle with ipads its kind of scary. Anyone have any thoughts? Anyone switch from 3rd gen to mini, and if so how was your experience?
