Took mine back. It was really a wow factor. So light, so beautiful. But in the end, it just wasn't for me. After spending a day trying to hunt down USB C adaptors in Apple stores (wasn't available at BB, where I bought mine), I got to thinking about what I loved and what I didn't. #1 Is this an awesome machine? Yes. #2 Is it revolutionary? Definitely. #3 Is it worth the money? Of course it is, if it suits your workflow. In the end, #3 did it in for me. It's a marvelous, wonderful machine. I just bought the wrong product for me because I WANTED to make it work for me. Could I type on my lap with it? Sure and watch the screen jiggle on my soft legs. Turns out a 13 or even 15 with weight is more stable for me personally. Ports is an issue for a user like me. I knew that going in, but I was going to be patient with it. It finally got to me. But that doesn't mean it isn't for you. I wouldn't mind one instead of the iPads we have, but I'll wait until the price comes down. It just didn't feel like a step into the future for me. It felt like like some steps back from my 13rMBP or 15MBP. Gone were the Apple touches I felt were worth the premium. I know I'll catch flack for this, but it felt like an iPad running OSX with a great trackpad and great keyboard for light typing. But then I started trying to touch the screen Magsafe? I need that. I really need that because I'm clumsy. Light on while charging? I really liked that. Bulky unibody? It gave me confidence that the investment would last. Mushy keys? Okay, at least my pinky and ring finger weren't getting sore. HDMI? Yes. USB? Yes, all my thumbdrives will still work. Thunderbolt? Yes, my firewire audio will work. I am also curious about the amp that drives the headphones. Output to my ATHM50s were crisp in my 2012 rMBP. Not quite as much in the 12 rMB. But, those onboard speakers were heavenly. Anyway, if you're like me and really have a lot invested in external equipment that uses ports, if you type or work more than 40 hours a week on it, and you don't ride in airplanes or meet clients in the field all day, then seriously think about twice about trying to fit a round peg in a square hole. In the end, I stopped chasing adaptors that aren't in stock in Apple stores and just exchanged for a new 13 rMBP. Just like my old one, but now faster and with "staggering" battery life. Oh, to those that have the rMB, congrats on a fine machine. One day, I'll come back and join the party, it's just not the right time for me. In my few days with it, I have come to respect the rMB as one seriously impressive machine.
