I love the fingerprint feature to buy apps in my iphone 5S, not to mention unlocking the device, soooo sweet! Do you think Apple will intruduce the Touch Id sensor in the upcoming Haswell rMBP? Do we need this feature? is it safer to unlock your Macbook with touch id sensor than using a "Regular" password? I´ll be pretty amazed if Apple put this Touch id thing in the next rMBP What about you guys?
