First I don't like apple.
Second When there are docs and or programs to share, USMLE, class, ect it's all windows based. I had one student complain that an EKG program a professor gave me to copy and give out was not "Apple friendly". Lastly you will pay a lot more for an APPLE.
Hey man
I love my mac. It never crashes, runs all the programs I need, and looks cool. I have yet to have a problem (knock on wood).
If you really can't live w/o pc apps, then you could always get virtual pc. I got this program, and used it plenty at first. Now that I know how to use my mac, I rarely ever turn it on.
