Paint.NET: The Anti-GIMP?

Arno contributes a link to Paint.NET, a free-of-charge raster-graphics program for Windows XP machines. "Quote: 'Paint.NET is image and photo manipulation software designed to be used on computers that run Windows XP. Paint.NET is jointly developed at Washington State University with additional help from Microsoft, and is meant to be a free replacement for the MS Paint software that comes with all Windows operating systems. The programming language used to create Paint.NET is C#, with GDI+ extensions.' It really seems like a nice tool. I definitely prefer its UI to GIMP's."
