I played with iPad 2 at Apple store yesterday. Yes, it's faster and lighter but since I won't be using heavy apps or games, I think iPad 1 will work fine for me. Plus, I am not too crazy about the new design. The exposed dock is so tacky. So, my question is if I get a refurbished one, will I see a huge difference than a new one? Will see I see lots of scratches or dents? What about iOS performance problems? TIA.
