I do all my work on a 2015 MacBook Pro.
I wish I had one of those. I have a 2012 15", last model with the optical drive. Have loved it, but has been acting out lately. I don’t want one of those P.O.S. low-travel keyboards or to pay for the gimmick bar, though. Hopefully it can make it until the next-gen model is released, whenever that may finally be.
