What made you go for the iMac and not the MacBook Pro with Retina? I'm mean, both are powerful, have great GPU and will get the job done. I use the iPad for almost everything, and Macbook has small SSD/HDD, can't use as a entertainment center. Almost never leave my home to any place where I need CPU Power and development software. I plan on buying a new Macbook Pro in a couple of years though. What about you?
