I just received the new updated MBP 15inch, 2.6Ghz, core i7 (non-retina display) after I cancelled an order for the new Retina MBP, the 3-4 order wait was very dissapointing so I swithched and configured a new updated MBP 15inch, 2.6Ghz, core i7, 8GB RAM, 1TB HD, hi-res glossy display at 30% less cost. It shipped in 1 week and I have been using it for a few days now. It is awesome!
I have iPhone4, iPad2, (mid 2010) imac 27, ATV2, MacMini Server and my wife has MB Air 13 inch - my point is this........why has everyone overlooked the updated the stunning current 15 inch MBP over the retina (which is suffering 1st generation hardware issues) it also suffers from a very long delivery delay, is very expensive and there are a lack of apps supporting retina - I acknowledge they will come in time.
The 2012 updated MBP I have now is gorgeous to look at and has a jawdropping display, yes it's display is awesome, Apple never made 'bad' displays! The core i7 ivy bridge CPU is faster than lightning and broadly the spec is same as retina MBP (bar flash memory & optical drive etc).
I have been running Windows 8 on Parallels (VM) without any degradation in performance on OSX or Windows, in fact it is unoticeable. What a perfect solution to all computing woes. I am so happy with this laptop I could cry - it entirely completes my life in the Apple world I live in (& supports the Windows side if required) - for those struggling with the high cost of the new Retina MBP I strongly recommend you seriously consider the updated MBP 15 inch over the Retina, even the extra 20% weight is not an unsurmountable issue - you will definately not be dissapointed.
Consider this option and save serious money too (I can wait for retina once it is established) - from one extremely happy Apple customer
