regarding flash killing battery life...
remember when everyone was saying that multitasking was going to kill our battery life (a notion created by good ol' apple...) and well that simply was not true... lets wait it out and see what happens... I agree flash is a resource hog, but perhaps adobe has figured out some power saving techniques and perhaps it will not be as bad as you think... keep in mind I have a feeling the pre will have a tap to use flash system similar to when you get a flash blocker on your computers web browser... that way flash is not going to just overwhelm your system... you use it when you want to use it... that makes the most sense IMO...
