Mine was a 2010 base model, but by 2015 I had grown weary of it's limitations.

The form factor was just amazing, and even though the Core2Duo CPU wasn't anything special, with the SSD (at the time, they weren't very common) it was still a very usable machine. The battery life was my biggest complaint, only about 4 hours, and they didn't fix that until 2014.

Still using mine. It's great. I'm gonna be really sad when it falls out of the supported lineup.
