[freeza]

None of these were deal breakers for me but:
Flash (most missed feature)
Camera (is tolerable with tweaks)
D-PAD (probably a feature I would want back the least. it would mess with screen real estate. but still, maybe if it were like the LG Expo then we would have something.)
Soft-reset hole (I hardly ever use it, and i'm assuming HTC was confident enough in the stock rom/their software that no one would have to use it, and this is true. I only started needing it when I flashed custom ROMs)
