I'm currently using MoRu as a Finder add-on. It makes the whole Finder experiences much more tolerable. Well worth checking out, the only shame is that it's not intergrated IN the Finder, otherwise, just perfect.
Apple also has a patent where the whole screen functions as a camera. Now wouldn't it be cool if the new iPod is also capable of doing photo's/video through this screen? That and a cell-phone and I'm a happy camper.
