As the title says, I bought an iPad 4 for $458 on black Friday. 2 days prior to that, I had received the refurbished iPad 3 I ordered from apple store(amount paid:$379). Both are great deals, but way too similar in features to warrant keeping more than one. So far the major real-world differences i've noticed are: -iPad 3 seems to run "hotter" than the iPad 4, which stays relatively cool over long periods of use. -iPad 4 loads online videos faster, specifically with YouTube. I noticed a 5 second(give or take) difference in loading times during several side by side comparisons. -lightning connector is definitely preferable aesthetically speaking, and with ease of use as well. There weren't any other perceivable differences. Web pages load at the same rate. Videos look smooth and beautiful on both. Everything seems about the same except for the "twice as fast processor" and "twice as fast wifi" which I don't notice because I'm not running on a t1 or using my iPad as a server(I'm sarcastic but still objective). I know there's gotta be a use, I just don't see it. Does anybody have any similar experiences? Or perhaps know why the iPad 3 was discontinued other than the fact it would undercut sales of the iPad 4? Is the 4th gen upgrade worth $80. Anyone go from a 3 to a 4 and never look back?
