This stuff is great for developers, or users with vital "must have apps" that they need to run for work, say.

I strongly believe that new adopters should stay away for awhile...maybe a couple months.

And for heaven's sake DON'T do something silly like run outlook in a VMwindow. Stay the hell away from windows browsers. Learn the new conventions and paradigms. Use the Mac apps. Once you master them and internalize the way things are done on the Mac, you'll find you need none of the old crap anymore.

And If gaming is your thing, dual booting is the way to go, because a VM solution is always going to impact you in the types of games you are interested in.
