It looks like the next version of iPad will be getting the TouchID feature to further secure the device from theft, but what about Apple laptops (and desktops)? It's something that makes sense, but will Apple ever implement it?
Are you shutting off and turning on your computer so often throughout the day that you need Touch ID to log in multiple times an hour?
If you want a fingerprint reader, they sell for; very cheap.
I'd imagine that people who use laptops would find such a feature very useful, especially when traveling, or in general, when leaving their laptops unattended. Turn on? Use TouchID. Wake from sleep? Use TouchID. Laptop stolen? Have to use TouchID.
