I switched to Mac with the Mid-2012 i7 Air. Cost me just under A$2000 after updating all the internals It is still my home computer and have not noticed it slowing down! I'm glad I chose this over the newly released 13" pro retina. The low DPI screen means this thing flies! I can't see any reason I would to upgrade in the next year or two - appart from a new battery, and my power adaptor just started fraying. A new Air wouldn't be significantly more powerful & would cost more than my original (Australian dollar doesn't convert as well now). Although, having just got into audio production, I think I'm almost at the performance ceiling. CPU fan gets quite loud while using Logic with 15+ tracks & effects, but it still runs great. I need to replace the battery - I think this will make it like an new computer.
