Well thanks for your feedback!, well actually I will have windows and mac, but this is like a new workstation, for example on this " p4 1.5ghz 256 ram", like the LIGHTING in MAYA, is so slow, for example, if I do like render with good lighting, my pc will just like die, windows will die and everything will die! hehe, that just wil result in a manual reboot.. So, I want to avoid this, but well, some of the CONS is that, I've never worked with Macs before!!!!!! BUT I find that exiting and I want to learn, and like Its not gonna be that hard (i'm a linux system admin too, I used to have a job on that), so well, the other good thing is that the mac has the DVD writer, and 128meg video card, and basically just between us (I want the mac ) but I need to know the reality and see what I need to really choose. Well thanks, every feedback is welcomed and nEEDED! THanks! Carlos.
