Can we just like, stop here and prevent this going into a Mac vs. Pc thread? We all know its a pointless debate. It's all about the user, personal preference. It is true some things might perform better on certain systems. It is true some things are cheaper than others. Both platforms have their good and bad sides.
In the end, most people won't really care what you used, as long as the stuff you do on it is good. Whether that is music, arts, whatever. What matters is, you need to feel confident with whatever you are using - that is whats important in creative work, in my opinion. Whether that be a Mac or Pc - up to you. Same thing applies to DAW's, software plugs, synths and god knows what else. My 2 cents. //rolls down the stairs
