Windows Hello (any machines with right hardware)

MS recently revealed Windows Hello, which uses biometric information to authenticate users. I am interested in this feature (and am starting to look around at new laptops since mine is dying). Now, Windows Hello will require hardware that can read some form of biometric data. There are fingerprint scanning laptops. That is not new (though it seems like some of the best ultrabooks out there don't have the capability). Anyway, the feature could also use an illuminated Ir sensor or iris scanner.

So, I have two questions... what is the best existing ultrabook with a fingerprint scanner. And... are there machines with illuminated ir sensors or iris scanners built in? Both seem like newer techs that maybe haven't made it into consumer devices... am I right?

I would be careful about using biometric readers, unless you just want it for the convenience. For real security, these are not well proven yet. What's more, you can be compelled by police in some jurisdictions (like the US) to unlock your devices with biometrics where they cannot compel you to unlock a laptop or phone with non-biometric means.
