I may be wrong on the terminology in the title..
But I've just purchased a new Macbook Pro, and I can't decide if I want Bootcamp or Parallels!

(don't even bother with any Mac jokes.. heard them all. )

So if anyone has any expertise with the software, the help in determining which to go forward with would be very much appreciated!
OH! And if I were to choose Parallels, which Windows version?
