There's a cool new offering on MSDN now that enables people to give TFS a try without having to deal with downloading it or installing it or almost anything.  I tried it last night and all I had to do was go to the site, download some small ActiveX control and use the demo.  It included a sidebar script that walked me through step by step on what to do.  It was a great way to try out VSTS and TFS.  Here's a link to the lab.  Also, here Rob Caron has more to say about it.

Enjoy!
