I will not be able to get the next haswell pro. Period. Out of my hands due to region specifications, and needing a laptop immediately within a week. I'm looking for something to last me 4-5 years? I was considering this 13 inch rMBP or the baseline 2013 air(( cannot upgrade ram too for same reason above). Not sure what to do.. I'll be using it for engineering, and will run windows on it via bootcamp.
