ProHealth, I would keep what I have, if I liked it.

I don't like Vista so I have been using Window7 RC exclusively since February. I have had absolutely no problem with it. With the XP virtualization mode, I can now convert ALL my machines to a single OS.

One of the labs we use has an applet which does not support Vista, so I have one machine that is still running WindowsXP. Well that's history, because the app is now installed under XP virtualization and it works just fine.

There should be no hurry to upgrade, however, the OS will not be available commercially until October.
