Don't think I would do it just yet. It is only in beta form release candidate 2. Mostly for testers and developers.
I would wait until the actual release on windows updates comes out and even then I would wait for a while to see what bugs may still be in it. Let a few others play with it first and see what is reported and then make up your mind on whether to install or not.
I waited almost 6 months before I got brave enough to install SP2. Apparently that was a good thing.

Now go have a great night.
