Seems like several threads are riddled with people answering questions about these and referring to the Retina models. So, let's start a thread where we can discuss the questions and issues around purchasing the new (2012) NON-Retina 15.4" (NOT the 13"!) MacBook Pros.... For me (and I don't want to open a debate about this!), these are just what the doctor ordered. For specific reasons, I need/want the SuperDrive and eNet port onboard as well as the native screen real estate of the HR w/ Antiglare. I bought a late 2011 Refurb last week hedging bets in case they went scarce and now returned it yesterday to BTO one of these new ones because the improvements look significant enough! One comment/question: It looks like they are spec'ing faster 1600mhz RAM. Anyone know if current model 1333 modules will still work and/or what the real world difference might be? Also, the chassis appears to be identical physically. Anyone know if the thermal systems got tweaked at all internally (different quieter fan blades, etc.)?
