At some point in my keyboard-optimizing phase I decided that trying to find the ideal keyboard was the wrong approach. As long as it's a mechanical keyboard, I'm probably happy enough, and really from that point my optimizing was just novelty-seeking. So I kept my final two mechanical keyboards: a Razer one with blue switches, and a Corsair one with red switches. When I get the itch to get a new keyboard, I just switch from one to the other. They're both pretty good keyboards, and I figure that the variety is probably a good thing. I probably switch 2-3x per year.
