oem comes without the fancy packing, but pretty much the biggest difference is that with oem you can't upgrade the mobo (that is you have to have the same mobo, but other components may change), with retail you can upgrade anything you want.

Actually, for a limited time only (sounds like one of those 'but wait' TV commercials)... For a mere $50 a pop you can get two 'Home Premium' licenses... Its actually a really good deal if you have one or two more PCs to upgrade. I'm doing it with my soon to be had HTPC and my wife's computer.
