I anticipate that, now that Thunderbolt 3 is out and available in
a mainstream Mac, other manufacturers will ship more new high-end
computers with Thunderbolt 3 and USB-C. USB 3.1 Gen 2 tops out at
10 Gbps, which will be fine for lower-end systems, which don’t
require 40 Gbps performance and aren’t intended to support more
than two displays. Mobile devices outside of the Apple ecosystem
will stick with and continue to adopt USB-C without Thunderbolt 3
for simplicity, power consumption, and controller cost.
With nothing else like either USB 3.1 Gen 2 or Thunderbolt 3 on
the horizon and the broad industry support of the USB-C connector,
USB is finally living up to the Universal part of its name — even
with Thunderbolt thrown in on top.
Great explanation of a surprisingly complicated situation.
