The (official Microsoft) keyboard for the Surface 2017 doesn't appear have a fingerprint sensor, and that there are SP4 keyboards with and without the sensor. I've never had a laptop with a fingerprint sensor, but find the one on my iPhone to be quite handy and suspect I'd use it on the Surface Pro, as well. What's the story behind why the new Surface Pro keyboards don't have the sensor? Did it turn out to be unreliable/problematic? I'm very close to ordering a Surface Pro 2017 but ordering the "old" black SP4 keyboard just to get the fingerprint sensor.
