What's the best computer keyboard ever made? For me, an old favorite was Microsoft's Natural Keyboard Pro, but the 30-year old IBM Model M is the only answer for some mechanical keyboard enthusiasts. Wired recently profiled Brandon Ermita, who restores the Model M and sells the five-pound keyboards to diehards. And while it's not peculiar to have a favorite keyboard, there are also users who covet rare vintage keys. The story of the Cherry Red Doubleshot Esc key follows that obsession. But for those of you who want the feel of a mechanical key without the clickiness, Cherry and Corsair announced the MX Silent switch last week.
