On a marginally related note, I so wish Microsoft would offer free Spoon'ed IE6/7/8/9/10 executables instead of those humongous Windows VMs they have on http://modern.ie now. Spoon is perfect for solving this problem, and even if you only directly help Windows devs with it, I bet many devs on OSX/Linux have some Windows VM lying around somewhere. (Spoon actually offers this, but at a steep price)
