I think the better question is why do you need LTE on AT&T now? How much area did they cover so far with LTE? If their HSPA+ is as good as they claim to market it as 4G with 21Mbps speed, how much is the speed gain from LTE? As for the screen size debate, a lot of folks are still overlooking ppi issue and merely looking at physical size as I mentioned before. Bumping up screen size hurts sharpness if it doesn't come with resolution increase. I think 4.3" is already pushing limit for WVGA resolution. You really need at least qHD or HD resolution from 4.5" and beyond.
