You may want to reconsider, at least with the base model. Although I doubt a little higher clock speed in the mid or upper models will help much anyways. Just picked up the new 2.7GHz 8GB rMBP 13 tonight. It took me 7:12 to export a 4:08 422MB 1080 file at the default medium quality setting in iMovie. Thats nearly double the time of the video clip. Uploading a 1.26GB file with 427 JPG photos from an SD card with the built in reader took 1:32. I don't even want to know what working with 4k video and full sized RAW files in CS6 on this thing is like. I am very disappointed that a $1300 Macbook with PRO in its name in 2015 performs this poorly, its really inexcusable IMO. This is what I would expect from a MacBook Air, not a Pro. This plus the new Macbook release is pretty disheartening. I don't get why Apple thinks their entire user base is full of nothing but people who only surf the internet and check emails on their computers. There are a VERY large numbers of professionals like me who seems to be getting the short end of the stick as Apple keeps moving towards what are basically iPads with keyboards and only the top of the line, insanely expensive model is suitable for any kind of real photo/video work. This is the kind of stuff that will have more and more of us seriously thinking about (as much as I hate the idea) a move to Windows laptops. Taking this back and hoping for a new quad core sometime this year.
