I lovelovelovelovelove my Macbook Pro!
I would never go back to PC. It doesn't take that long to get used to... the only real differences are the menu (there's no start menu on the bottom, you have a "finder" etc) and the 'x' on the top of your browsers is on your left, rather than the right. Those were the only 2 main things to get used to for me.
Macs... no virus programs, no need to clear cookies or discs every day, no viruses, fast downloading times, no freezing up on you! Sooo easy and user friendly. You can get a regular Macbook for only $999 now. The 13" Pro is around $1200.
I would suggest finding an Apple store or a Best Buy where you can play with one. They're fun!
