I got an iPad 3 this Christmas. My gf ordered it a little too close to Christmas and anyways it just arrived today. I haven't opened it yet. I'm considering returning and it getting the iPad 4. Is the iPad 4 worth the upgrade or should I go ahead and open my 3 and say forget about it. It would cost me about $100 ish with taxes and all to upgrade. Is the iPad 4 processor worth the $100? Happy New Year everyone!
