After months of eagerly awaiting the release of a stand alone keyboard with Touch ID I am happy to say it was worth the wait. It's a subtle and refined upgrade. It feels dense and robust. It's only slightly heavier than the MK2, yet the difference is quite noticeable. A+ for build quality. Another thing I like is that the bottom is now matte. No more hideous scratches! The pads seem to have a stronger grip as well. Another thing a lot of people don't mention is the tactile feel of the Touch ID button. It's clicky and stiff. It feels just like the button on the MacBooks. It was quite a pleasant surprise.Touch ID is fast and responsive. I love how quickly I can lock and unlock my Mac with one button. Overall I'm very impressed. I really can't see myself going back to another keyboard after using this one. I've always loved the Magic Keyboard, and Touch ID has taken it to the next level.
