yes, macs are expensive...but well worth it in my opinion.
they are a graphic artist's 'dream machine'. Most universities and colleges that teach fine arts and graphic design use macintosh.

the only problem that i've had with my mac is that it used to crash several times a day...i simply installed more RAM and the problem was solved, although it still crashes when i am trying to juggle too many applications at the same time. When this happens i allot more memory to the apps. that i am using and it never crashes. Just in case, get in the habbit of saving your work at regular intervals and you will be fine. It will save you from having to redo a project and may even save you from getting a few headaches.
