i wanna share about this in considering Mac. I m a graphic designer and I do use my MacBook pro a lot. The main thing is. The visual graphic quality of a Mac is very close to printing quality. Adobe works very well on a Mac.
Other than that, u cannot use pirated software, u cannot play most of the games. So if your work involves mostly Microsoft office, u should just get a PC.
To me, if you are using bootcamp most of the time on your Mac instead of the Mac OS, your are pretty much a poser. Just my 2 cents.
