Hi guys (and gals)! I am thinking about buying a 13inch MacBook Pro, but am curious as to how "current" the specs are (processor, etc) on the 13" models; ie. Is there potentially going to be a big jump in peformance over the next year or so? I currently use a mid 2012 11" MacBook Air but the screen size and quality (and battery life!) has really been bugging me lately. How much of performance improvement would a mid tier 13" RMBP be? And how "future proof" are the current models? I know, as far as performance goes, the 15" are the best model to buy. But I like the 13" form factor and here in Canada at ridiculously expensive to get even the base model 15" And insight would be appreciated!
