I'm looking at both, trying to figure out which one I should be getting when I eventually bite the bullet in the next week and replace my current iPad. I can get the 4 for cheaper, which is good because I'm low on cash. Is the Air phenomenally better? I don't mind about a weight difference, I'm a big man that can hold that much weight IN ONE HAND. :O Anyway, it comes down to at least 130$ difference between the two. Is the extra performance worth it? Does the screen look better? Are the speakers on the 4 bad/the 5 have so much better speakers?
