My five year old 13" MBP is starting to die on me so I'm considering selling my 5K iMac (which I never use because the screen hurts my eyes) and get the top stock 15" rMBP + a decent external display. It should be about as powerful as the iMac but be able to replace my MacBook Pro as well. I know that there seem to be new thinner MBPs coming fairly soon. And while better portability would sure be nice, I'm a bit worried that they will sacrifice things to make that happen. Plus a full redesign could potentially introduce some issues that won't be resolved until later releases. The current design is very refined already. But the new machines might very well not be a compromise and just better all around, so there's the usual worry. Since I'm in fairly urgent need of a new computer I can't wait more than a couple of months. What would you do in my situation?
