What were some of your observations about iOS versus android?
Personally I've had both a iPhone 4 and I own a iPad mini. I then upgraded to a iPhone 5, but sold it a month or two later because I was hearing so many positive things about current android.
While I do t believe android is perfect, I think I'm going to stick with it. I think android is more future looking than iOS and apple are it now, and that gets me excited. I'm really looking forward to the next nexus 7 being released (hopefully soon) to give that a go.
Honestly, some of it has to do with budget as well. I like that android tablets are usually cheaper.
Although, I'll still take a MacBook over a windows laptop any damn day. Heck, if Macs actually had a compelling gaming ecosystem I'd probably go that as well. For everything other than games I think macs are better.
