But if you read what I said, I didn't say the Classic made for a bad user experience, quite the opposite, and as I said, I loved the 17" I owned. I said in my experience that having the retina display and thinner profile made for a better experience overall, which another poster seemed to disagree with.
His point about USB ports is fair enough, but I can carry a multi-USB adaptor if I'm really going to lugging the whole show in on the road.
The price difference also isn't that great when you factor in the SSD and panel tech. You also indicated that you have a quad-core pro, so it actually doesn't have a user-serviceable battery, the only difference is that it isn't glued in.
Incidentally, I am quite pre-1990s...
