The Logitech keyboard was conceived, designed, and engineered with great care and attention to detail. The result is a model that has exactly what the user needs. The best mechanical keyboard for Linux uses analog optical switches that respond to your actions at the speed of light - literally: optical switch technology involves using a light beam. The frame for the keyboard is the brushed aluminum-magnesium alloy top case. I want to get such a keyboard for free, but on the one hand, I would rather order it on Amazon.
