I work on mac for 10 years in my job (graphic designer) and I took the risk to issue court to pass on to the pc at home mao. Let me tell you I sold my pc for mac redeem myself a second hand. After a year, because there is no stability level photo, it's expensive, but it is a mac! The last system, OSX Panther, works very well on my machine (G4 466), and this is a monster of stability and usability. The report qualitprix a nine G4 (although there remains only one model for sale on apple store) is pretty good given the quality that unfortunately too expensive for many scholarships. The advantage of mac is that you can purchase 'machines that are between 2 and 5 years, and still allow to work without feeling too prehistoric.

That's it.
