I have Microsoft office that I purchased separately for my Mac (Office for Mac). But after learning my Mac I realized that I could have used iWorks for the same purpose. I don't have parallels on my Mac. I've read reviews that said that the windows program freezes, shuts down and subjects your Mac to the same worms and viruses.
Then again, Mac computers can be booted in Windows now (though I fail to see the real point in running WinXP on such a beautiful computer) so you can technically run absolutely ANYTHING on a Mac.
I agree!
