I have always been a tower/laptop guy. But this computer is changing the game for me. After comparing it in-store to a similarly equipped Mac Pro on FCPX with the same video files, the rMBP won hands down. It was not just slightly faster, it was MUCH faster. I suspect this may be why we are not seeing much in the way of updates for the Mac Pro. Apple may keep the Mac Pro around, but I think I will get a rMBP and be more than happy with it. In my opinion, the rMBP is a potential game changer, but I am waiting to see how it holds up and what users think of it a bit longer term. Thoughts?
