Mmm...I'm using Yahoo Widgets for my Windows XP Desktop. Pretty nifty I would say. It pretty much works like Apple's widget features, not much I can say about that. A comparible app would be the google one, but I like Yahoo's aesthetics more. The widgets I mostly often used Due, Newsstand, and Weather XD.
Yahoo! Widgets: useful, fun, beautiful little apps for Mac and Windows
I also use FileZilla to do any FTP things, like working on my college account off-campus.
