Stickies for Windows. Stickie-note desktop applications aren't anything new. But I think Stickies for Windows is worth a mention anyhow, seeing as it's written in C# and licensed as freeware. Now, I don't assume an application is going to be good just because it's written in C#. I am finding, though, that I am a lot more willing to try out random utilities written in one of the .NET languages than otherwise. ... [Larkware News]

This IS a cool program.  I use the "Official POST-IT Notes" version, but I really like Stickies' understated interface better.  I'm going to give it a whirl. 

BUG: Stickies doesn't understand multiple monitors/negative coordinates.  I've moved my stickies to the left monitor (-coord space) and now they are stuck, and I can't move them back! :)
