I don't think the real message here is the fact that its a Smartphone screen. I believe the real message is that touch screens, no any screen for that matter can be a much higher resolution than currently offered. Yes, one of the major bottlenecks in phones since forever is the battery, but lets be honest. The battery is the bottleneck in many products right now. Ultrabooks, Electric Cars, Smartphones, heck even that AA battery you buy in the store is far behind where it should be these days.
