Yup, that's right, Windows on a Macintosh!
I installed it today using an application called Boot Camp. If you have a Intel Mac and a "bona fide installation disc for Microsoft Windows XP, Service Pack 2, Home or Professional" you can easily do the same.
It took around an hour and most of that time was for the Windows XP installation. Everything went smoothly without any problems!
Right now I'm using the Windows-version of Firefox with the MacFox-theme that makes it look like the Mac-version of Firefox, on my Mac! Weird! Weird! Weird!
Everything about this is really weird! You're not suppose to run Windows on a Mac!
This it what it looks like:
It's very easy to change between Mac OS X and Windows XP. All you have to do is hold down the options key when you boot and then select which operating system you want to use.
Why install Windows on a Mac? Because now I'm able to do something I haven't done since Christmas 2002 (I think). I can play Harry Potter-games on my computer! I can now play old PC-games that's been laying around useless for years! The Sims, Roller Coaster Tycoon etc. I'm so excited!
And now I'm gonna go play Harry Potter and the Chamber of Secrets on my Mac :D
