I found keeping my Yubikey Neo on my actual keychain to be a bit inconvenient, but wearing it around my neck like a dog tag has worked great.

Sadly, I've been unable to convince my wife that it's worth it. She won't wear it as a necklace or bracelet, almost never has pockets, and rarely has her keys near her when at home. I might just have to stick an Edge-N in her laptop and slip an Edge onto her keychain, so that when she inevitably calls complaining she can't log into GMail from a friend's computer, I'll be prepared...

From a development perspective, I've read through the U2F spec, and it seemed quite reasonable. I haven't had a chance to try implementing it in anything, though.
