I have been waiting for this machine to come out for a while, and I don't like the steep price of the 15 inch and want more portability. I use my Mac for a few pro level stuff such as movie editing and Image editing. The specs of the 2011 13" cMBP I have are fine for my needs, but I want something more portable, with the same / better specs than the one I have. So after looking at the price etc of the retina 13 inch, I am quite happy with the base model. However, the only thing I am worried about is the processor not being Quad Core. I noticed that this year, Apple has updated all macs (apart from the Air) to a Quad core Ivy bridge, which is very similar to what they did with the 2010 refresh (13 inch pro was left out of the sandy bridge processors until 2011 refresh. I am quite happy with the speed of dual core, it gets the job done. However, the fact that Apple could add a quad core when Haswell comes out is making me reconsider, because it feels like the Mac may be outdated very quickly (Possibly future OS's will only support quad core, etc.) like Mountain Lion has recently dropped support for some Core 2 Duo Macs. It's also a lot of money to spend on a machine that has the possibility of having an outdated processor type. I plan for this Mac to last me at least 3 or 4 years, so want the specs to be decent. I know that obviously the longer you wait, the better the machine gets but I would like to know whether it will be worth waiting for this (Possible?) upgrade to quad core. Or do Apple have no desire to put a quad core in the 13"? Don't quite understand why they didn't this generation especially for the price of the Mac. as said before, every other Mac line has it now. So, buy now or wait?
