I just noticed that VS2011 includes an exploratory testing tool. Anyone downloaded the developer preview yet and had a go? At the moment I find pen and paper (and maybe a few dayglo markers) to be a pretty streamlined tool for exploratory work, but I'm always willing to look at tools that might benefit me.

FWIW, I found the transition from VS2008 to VS2010 impractical until they got the first service pack out, but at this stage find it to be a fantastic working environment. Hopefully the first release of VS2011 will come out without any major hiccups, as it looks like a worthwhile progression.
