parallels
I own a mac IBook and really like it. However, I have few applications which run only on windows. So I finally purchased parallels and am now running windows on it. So far its been pretty good. However one thing that I noticed is parallels really hog up the memory and CPU. If you are planning on running it and doing other things on MAC you might not be pleased at the performance.
I think now I can get rid of my old Dell laptop
