Is it wise to get an iPad 2 rather than the new iPad or the unreleased iPad? Is the Retina iPad really THAT much better? Say..$150-200 better? Right now I'm looking at a 32GB iPad 2 for about $470 in mint condition. I went today and played with both at bestbuy and side to side compared. The retina was beautiful, but the price to me wasn't. I always feel better about my purchases however when they are the newest and a little bit more future proof. Thanks.
