yep, wearable, like a ring would be a clincher.

I really like Yubico and fingerpring scanner is an awesome idea, would be really happy to bring my fingerprint instead of relying on laptops. On the other hand, a wearable would be a whole new level, like thinking 2 steps ahead

I could see Yubikey going to a NFC ring at some point. For PCs all they would have to offer is a USB NFC transceiver.

There are probably still some engineering challenges getting all the cryptographic functions and NFC power transfer into the form factor, but it seems like those will get easier over time.
