It really is a better option not to buy a mac right now. All the new laptops have crap screens in them, not to mention other things wrong in them. Just wait for revision two and snatch one if you're really set on a mac, everything is usually fixed by then.

Though in my opinion, I prefer PCs. I've custom built my desktop and its not had one fault since the build day. No software bugs even. Even though macs seem to be the norm in the graphic/web deisgn world PCs are better suited for it in my opinion :P .
