What a difference to have a modern Mac! My 2009 had been struggling for 2-3 years - it was pretty awful. I love everything about this one except that it's a little large for me - it kind of wobbles on my lap. Fine with a lap desk, though. Does everything a Mac should and almost as light as my Lenovo Carbon Lite from work. I do miss the the black around the screen instead of silver, but that's a quibble.The magnetized power cord is better than it was in 2009, but I keep knocking it out. Essentially, that's a good thing, it a little annoying.I have some annoyances with the current system, but that's nothing to do with the hardware.I'm a little nervous about the limited onboard storage. I don't want to use iCloud - it's always deciding that my password it wrong (it isn't - I use 1Password) and they recovery is brutal. It always takes several changes until it sticks - and then I have to change every other Apple thing separately. Drives me crazy. Anyway, I put my whole old computer's drive-worth on here and it's fine, so maybe I shouldn't worry.
