Logitech's G512 X gaming keyboard is over the top and overdesigned, but in a good way. It's the company's first venture into analog Tunnel Magneto Resistance, or TMR keyboard technology, and the first keyboard to introduce a capability I've been waiting for: It lets you mix analog and mechanical switches rather than having to choose one or the other.  And while it's expensive at $180 to $200 (depending on whether you want the 75% G512 X 75 or 98% G512 X 98 sizes), it's not nearly as pricey as some models, like the $250 Razer Huntsman V3 Pro. I love the idea of the mixed technologies for a few reasons, notably because it allows you to customize the feel and responsiveness of the keys based on the in-game bindings and functions.  Analog switches in general support variable actuation points -- you can set the depth of the keypress at which it registers and resets, and you can set two actuation points, where the second is bound to another action.…
