Photographers. Photographers were still using that.

You know what my mid 2009 MBP can still do? Pull images from my DSLR while charging while plugged into a wired network, transferring them to an external hard drive under the command of an external mouse and keyboard, using an external display. No daisy chaining required, and the cabling is only a minor disaster!

(If I bought a Bluetooth mouse and keyboard, I'd be using zero USB ports for any of this. External disk is Firewire.)

On the other hand, the new MBP can do all that when you plug it into a big display at home with a single cable, avoiding the cabling discomfort. I like the Surface Book more than the new MacBook but I see its benefits.

That requires that I buy a display that works like that, and still limits the subsets of that setup I can use. Which comes up for me a shocking amount these days :/

In particular it's nice when my computer is useful without a bunch of extra crap plugged in, and mostly progressively enhanced by new attachments.

I can do light photo work on site with a 2009 MBP and no peripherals at all.
