Great thread, just read it through! Very good points about the technology and tradeoffs. Still my biggest issue is that almost everything scrolls badly. Browser in portrait mode is otherwise very fast & nice, but Vsync should be enabled, now the text is unreadable while scrolling (framerate is fine!). Could Vsync be hacked to be enabled somehow? I can't imagine that it would drop the framerate, Vsync doesn't need processing power.

Even with the current tradeoffs with transition speed etc the music still gets interrupted sometimes (one of the worst things seems to be if you have Jabber enabled for Facebook with a lot of contacts). Music should never be interrupted. Could the process priorities be changed somehow (safely) to force this?
