FIRST OF ALL, I have to give corky-g some serious acknowledgement for that signature. I think I may have a permanent smile on my face for that one ... 🙂
SECONDLY, a few of you may know that I enjoy partitioning as much as I do a good laugh. I think I'm up to 15 or so partitions on my 120GB monster. However, most of my partitioning can be attributed to multi-booting, as I am continually not satisfied with the FIVE OSes I've already got running on this thing. However, fo a single OS arrangement, I would only partition for some of the reasons already mentioned. In order to protect and preserve YOUR documents, MP3s, and such, you might as well move this information to its own partition. In the unpleasant event of a reformat, your data remains intact. Isolating swap space/page file to its own partition can prevent some serious fragmentation, yet can really impede performance.
