I have the same machine and very happy with it. I agree with the 512GB, but at the time the price difference wasn't worth it. I think the best thing is to have an external disk that can talk thunderbolt speeds and leave the rarely used things in there.

I've debated getting an external drive. Thunderbolt drives are still too expensive compared to USB3 ones. And I do like the fact that I don't need to carry an external drive with me if I need to see that one previous project since I find I do that occasionally to find some code logic or a solution to a problem in my previous projects.

They're still "rarely used", but td so convenient to have access to them always. I could get Dropbox but then I'm paying for data space monthly.
