I am using VM for a while now, most of the time to
have alpha, ctp, beta…

My issue was that my main VM was starting to be
really big: 8.5Gb and I had to do something to save some disk space.

If you are like me and you are using Groove. I recommend you to read Marc Olson’s
Groove “12” Blog.
Tomorrow Marc will blog about the integration of
InfoPath and Groove 12, such an integration is so promising.
