The Logitech Craft keyboard is what happens when a keyboard engineer glimpses Microsoft's Surface Dial hockey-puck peripheral and decides: We can do that, too. But if you want to spend $200 for just a keyboard, don't bother: The only way the Craft makes sense is if you see value in its Surface-Dial-like navigation knob that also integrates with Logitech's PC-spanning Logitech Flow software.
