Same here. The image sharpening software is remarkable, but you still can't zoom much or it gets grainy. The CPU and GPU have plenty of grunt, but that might change in 2 years and the next One needs to have the best, just like this one did. Sense doesn't seem to be super-heavy like TouchWiz or LG's UI, so that's a plus on the RAM/clock side.
What WOULD be nice, though, is a bigger battery. The One's battery life is fair but could be better.
