I just purchased my rMBP (2.6 ghz/16gb/512 gb) two days ago. The price is undoubtedly high, but I concluded that the productivity boost that it will provide at work(for its lifetime) was worth the $. While waiting for it's arrival, I've been reading through these threads to gather opinions about the rMBP, and I must say that I have never seen so many negative opinions about an Apple product. I admit that I did not find the "new Ipad" as revolutionary as promised, but I couldn't help my jaw from dropping as I followed WWDC on the "SoldierKnowsBest" llivestreaml. IMHO I thought no computing unit has made such leaps as the new rMBP. I mean 7 hours of battery life on a 15 inch screen is enough for me to want to buy it outright. My excitement for my new device is dwindling though from all the hate that many individuals have for this new generation of MBPs. Can some forum members please post about their experience with the rMBP. I specfically would love to read opinions about users moving from the 2011 model to the rMBP. Is the rMBP your new "can't live without it device" or could you easily transition back to your 2011 model in the blink of an eye? Thanks for all your help.
