Just bought a MacBook, because OSX is the ultimate Unix development platform. But I also had to buy a Gig-E dongle, and if you buy a MacBook Air, you have to buy a USB-C dongle, and an Ethernet Dongle, and none of your thunderbolt accessories work anymore.
The dudes at the Apple store say, "everything will be wireless eventually" well that's a great theory, but 1) It's not wireless right now 2) Even if it were, in a high density office environment, there is simply not enough wireless spectrum allocated in the USA for 200 users in a 35,000 ft^2 space to have a Gig-E wireless connection.
So stop the stupidity. Gig-E ports should be standard on your "Pro" models. Consumer or Home models, I understand the philosophy, but not on the Pro.
