Really, I do this for one reason. If, say, XP takes a dump and causes my HD to crash, I have to reinstall XP - I don't lose my music or graphic designs.
You could do that any ways, wether they are on a seperate partition or not. Partitions are just logical seperations to a single drive. If your windows system files get corrupted it wont affect anything else. Having a dual boot system is a whole different story and can save you time when fixing problems like that.
I use an OS partition and a general partition. It makes defragging a lot easier, and allows Windows to have a much smaller footprint to have to search for its files.
