CS5 will be formally introduced next week (but, rumor has it, won't ship until the fall) and Adobe has been posting sneak peeks of some advanced features, including this demo of the probably too good to be true Content Aware tool in Photoshop.
Having skated by on CS3 until recently, I am sadly behind the times in regards to PS's capabilities. But I can still make my own sandwich so this mock-demo cheered me up a bit.
