Phill Ryu's blog, "The top ten most beautiful OS X apps."

What would you nominate for the PC? I wouldn't put anything on the list for the PC that requires a non-default skin, etc.

Or, what are some of the ugliest? Freeware not included?

I can't find a single PC application installed on my workstation which I'd say was beautiful. Some cleaner than others, but nothing noteworthy.
