Unfortunately everyone that I know that needed/wanted a NEO when the original vote happened already have bought one but I just wanted to comment that this product has even more functionality than before!
You can now use your yubikey NEO in combination with a smartphone to generate a OATH codes, in other words where you could use google authenticator before you can now use the NEO instead. Since all the credentials are store on the NEO and not the phone it is not susceptible to malware like google authenticator and can be moved between devices much easier.
