I Need some advice, a few years ago i got a monster desktop windows machine for 3d modeling work... it's still a 'fast' computer, and it's got two 21" flat screens hooked up to it which i love working on. i've also got a macbook pro. i use the laptop all around, but when i'm in my studio i hook up my macbook pro to one monitor, have the other monitor running off my desktop pc... BUT I DON'T USE THE PC! For anything but itunes! i just don't like windows at all, what a surprise! (after a lifetime of macs!) so.... buying advice/selling advice.... just some thoughts.... r.
