Damn. I bought the standard.
Well, sit tight. There's a new version of the Neo that supports U2F (https://sites.google.com/site/oauthgoog/gnubby) coming out Real Soon Now (https://www.yubico.com/products/yubikey-hardware/yubikey-neo...) -- sometime in 2014 is all I've heard.
Step 1: Install the Yubico Authenticator from the Play Store.
Step 2: Install the OATH applet. Linux instructions are at http://forum.yubico.com/viewtopic.php?f=26&t=1159, but there are OS X instructions kicking around on the forums as well.
Step 3: Wherever you would normally use Google Authenticator, use the Yubico Authenticator instead.
You now have proper two-factor authentication.
EDIT: Wrong link...
