But don't worry, in 5 years it'll be ubiquitous, like USB-A is now! You'll see it on planes, busses, hotel room USB outlets...all those places which now have USB-A with 500ma charging which are now obsolete. The hotel alarm clocks with 30-pin connectors are especially hilarious to me, since they're "new" but already obsolete. It's still not reasonable in 2017 to travel and forget your charger, and it'll get worse (again) before getting better.
