+1 though this is raises the question of what resolution would be good enough. Ideally we would store images at the full display resolution, and try to minimise the storage space tradeoff by being more aggressive on compression. This would also open up an option for the illusion of fast starting Activities. iOS relies on this quite heavily as you start and switch between images, you're often looking at a transition animation and the static screen shot for a number of seconds (maybe 4 or 5 in some cases) while the actual code is still starting in the background.
