I'm sure glad I didn't buy my iphone for the LTE because I don't see much difference over 3G. Granted, I was getting 3-11mb of download on my AT&T iPhone 4S. Web pages don't seem to load any faster, music sounds no better, and videos look the same. And who is gonna bust their data caps downloading movies?
I get 40mb of download in Jackson MS and its no big deal really. No difference whatsoever from 7mb of download on my wife's 4S.
Or perhaps 3G on Verizon's notoriously crappy slow network was so bad that everyone assumed LTE was the only way to get decent mobile Internet.
