Mobile is a completely different animal. Many things are going to be sacrificed on the altar of mobile until we figure out a way to shrink humans by 200-300 %. :D I see that as a non-starter. Mobile is inherently limited and we are going to have to learn to live with it.

Seamless switching of state for live previews is desirable as a long-term goal, but are we ready to burn the house down and start over right now for the perceived benefits? Because that is what it would take. In any implementation I can envision, there would be a certain amount of robbing Peter to pay Paul on the performance side, no matter how the process is optimized. I wonder how that will play with the consuming public?
