I've resisted a tablet but am seriously considering the current options. The frugal part of me is saying to get a refurbished 32GB 3rd gen. iPad for $469 and save the $130 for something else. My concern is how much "better" the 4th is over the 3rd. It seems that the only thing noteworthy is the new processor, which Apple says is up to twice as fast, but that can mean that something that took a second now takes perhaps a half second. I don't play games and don't foresee using intensive video apps, so I wonder if the speed of the 4th would be noticeable to me. Am I missing something? It wouldn't be the first time! Any insight is appreciated. Thanks.
