Yes but any MacBook Air, not just one you've previously provisioned to recognise your fingerprint.
The selling point here isn't 'yet another external fingerprint reader', it's 'portable fingerprint-authenticated OpenPGP smart card'.

My main point though was that it's not a device-specific authentication, or even an external reader for unlocking a secret provisioned onto one or many devices, it is the sole thing needed, so you can walk up to a new device and use it without provisioning it with secrets.
An OpenPGP one would be cool though - replace passphrase with fingerprint.
