That's funny; I was reading a website that listed all the NON-APPLE laptop computers with TB 3. It was a quite impressive list!
Ah, here it is:

TB took awhile to catch on; but with TB3 and USB-C sharing a connector, it seems to be finally starting to live up to its promise.
And once Kaby Lake and later get going, it will soon be as common as bog-standard USB.
Then, maybe we can start seeing some non-asininely-priced TB peripherals, eh???
