so noob question, should I upgrade? I jsut got this iPad and was clicking though settings last night and it downloaded the iOS 6 last night, but I didn't install it because I was downloading videos too, should I install it? I am soo new to the iPad that I wouldn't know what I lost or gained with this, and just bought the thing Wednesday night (less than 2 days ago), I cannot believe there is an OS update that was not applied, should I just install this and go on with life?
