I'd really like a MacBook Pro remade like the rMB (slimmer than current, restyled, larger screen, and more ports than the rMB). I would be my perfect machine. However, you aren't going to see that until 2016 at the earliest, maybe later 2016. There is no way I could live without OS X until then. I use Windows machines at work so I'm familiar with them, I just don't like them at all compared to OS X.
