It is a good innovation indeed. That being said, I'd rather deal with the minor annoyance of having to figure out which way to plug my USB cable than having to carry two sets of cables/adapters to accommodate all my devices.
But even so, there's no tactile difference. So cabling a phone in the dark (pretty routine at bedtime) is a crap shoot either way. I personally solve this with a bedside dock, but it's a legitimate fault.
I've had a lot of non-conforming USB stuff pass my door and it's all really really awful.
Annoying wireless and iffy non-Windows support join the pack.
