Just thought Id write a message about my experience with the retina 15inch. Obviously these forums are largely for problem solving but after spending a month on here and also on the Apple discussion forums I think diligent 1st time buyers you can really form a warped impression of the products. Ive used powerbooks and macbook pros for the last 9 years and generally keep a machine for about 4-5, so when I get a new one its a big deal. I read about the early adopter display issues and returned 2 units before I got a Samsung screen (2.3 16gig). Id add that I never experienced IR but simply wanted peace of mind when spending so much money. Switching from a Snow Leopard Albook from 2008 I just wanted to say that this computer is such a massive step up on so many fronts. The screen looks BEAUTIFUL. The enclosure is so thin+light and I love the fact that the (for me new) unibody is now devoid of seams that generally separate over time. And this thing is fast. Ive barely seen a beach ball and when i stress tested it I had 4 HD movies playing, Logic with 250 tracks playing, encoding video in iMovie and every application running at once with barely a stutter switching between screens and using expose/mission control. For me more power would really be total overkill at this point. The speakers noticeably sound fuller and touch pad is much improved too. I especially like the new gestures and fullscreen mode. When on power squeezing mode using integrated graphics only, WIFI, brightness slider app if needs be I can ekk out about 8-9 hours of web browsing and music listening time at night (Im an owl). If i had to fault it Id say I preferred the deeper aluminum keyboard and the magsafe 2 comes out a bit too easily. I totally understand peoples frustrations with issues when theyve spent so much money but I just felt like writing this as Im sitting on the best computer Ive ever used in my life and its a thing of beauty. I just thought id speak up to the 1st time buyers that lurk with the story that doesnt get aired here so often.
