I came from a 2011 17" MacBook Pro. I got a 2.2 Ghz 15.6" model with a 1 tb SSD and 16 gigs of RAM. I do like the machine. The keyboard is easy to get adjusted to, no BridgeOS error yet (and it has slept a lot), and no crackling of the sound. Regardless, there is one thing I do miss. What is it? The way the power cord would wrap around the charger. It had the two little clips that popped out of the charger and I would just wrap it and be done with it at the end of the day. Now I just have it wrapped loosely in my backpack. Annoying, but whatever. It's a great machine. So light.....
