I don't have one yet, but from what I've read is the iPad 2 is still a great tablet and if you don't care much about having the newest retina display, the upgraded camera and dictation stick with it. It all depends on what you intend to use it for, if you're a movie watcher it's a great upgrade but for my wife who checks: Facebook, email and browses pottery barn the iPad 2 is perfect.
THis. just went in and checked it out both at best buy. The 3 is definitely sharper but i will not say i was "blown away" by the difference in pic quality. The pictures on the 3 look brighter and the text is definitely sharper, but the Ipad2 still looks amazing in my opinion.
I never owned an ipad so the experience is probably a lot different for someone used to seeing the ipad2 or 1 everyday for the past year.
