I thought i'd take the time to install the Windows 7 Release Candidate on Microsoft Virtual PC, and lo and behold, when I popped open Paint it seems that they've actually rewritten it.

Now it looks more like an Office 2007 app, but it includes Anti-alias drawing tools now, and more shapes. Because everybody loves paint.

I'm definitely getting Windows 7 at some point - the new stuff like Windows Media Center improvements make it well worth the switch.
