At first, I thought the Microsoft Office deal looked pretty amazing - I was strongly tempted to buy the academic version (I work at a university), even though I'm trying to get away from Office. But then I realized there's a "gotcha!" in the licensing.
The academic version of Office comes with three licenses, so you can install it on three family computers. The Special Media Edition, however, only comes with ONE license. So next year I'd either have to buy another license, or else pick which person doesn't get the new version of Office...
