I came from a Late 2008 MBP to the newest and latest Late 2013 15" Macbook Pro with 750M(and Iris Pro.) It has been awesome in pretty much every way, except on the of the main reasons I bought it: Using Logic Pro X (and Final Cut Pro X.) I've come to the conclusion that the GPUs in the rMBP are not powerful enough to drive the retina screen in these two applications. Scrolling and zooming in/out is slow, jerky and sluggish. I was hoping the latest updates to LPX and FCPX would alleviate this, but alas, no change. Seeing that FCPX is optimized for Mac Pro and is a video editing software, I dont expect it to run perfectly or even super snappily on a laptop, but Logic Pro X... It's a freaking DAW! Currently I have to run it in low resolution mode to make it not annoy the hell out of me. Even zooming in on a single track is not fluid in retina mode. Having to use low resolution mode kinda takes the sense of having a retina screen. Right now I wish Apple would have released a non-retina version of the 2013 MBP. I guess I was naive to think that these softwares would be optimized to run fluidly on one of the most powerful machines Apple has released. (Of course, rMBP's GPU's are no match for the Mac Pro.) Or maybe the time for retina is just still a few years away... /End of whiny rant I know I'm way past the 2 week return period, but maybe If I bright up my case with Apple it could be possible? Though, getting hold of a non-retina 2012 15" MBP would be freaking hard seeing as I'm not from the states.
