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.
I’m not a fan of the new keyboards either, but I think we’re stuck with them. I had a 2010 previously, which probably had the same keyboard as yours. Pretty nice to type on. The 2015 keyboard is shallower than that, but still better than the latest models. Not a problem at my desk because I use an external keyboard, but when lounging on the couch or traveling, it’s annoying.
I don’t mind losing the optical drive, but Apple’s obsession with thinner/lighter is wrecking core functionality now.
