First off, I want s/b to answer me this question. If I bring my iPod Touch 1G to Apple store and recycle it and buy the new iPod Touch 4G, will I get a 10% discount? If so, is it better to see if anyone is wanting to buy iPod Touch 1G from me for higher price? iPod Touch 4 8/32/64 GB 0.7 MP Cam Stainless Back Curvy like MBP iPhone 4 16/32 GB 5MP Cam Glass Back What are more significant differences? Not the price obviously, because all I want to see is 'what's inside'. BTW, I heard that the display isn't Retina display. FFS or something? Engadget has the comparison.
