After sensing something profoundly lacking from the modern typing experience, I decided to delve into the world of mechanical keyboards. As is the case with most fetishes, I discovered that there are entire online communities, cultures, and movements surrounding the magic of the mechanical keyswitch. I could have easily spent many months and several thousands of dollars acquiring, experimenting with, and reviewing all of the mechanical options out there, but with both time and money in short supply, I decided to focus on five specific models: the Das Keyboard Model S Professional, Filco Majestouch-2, DSI Modular, Matias Tactile Pro 3, and the Unicomp SpaceSaver M.
There is a lot of personal preference involved in picking a mechanical keyboard. Factors like key travel, clickiness, tactile feedback, weight, force, build quality and more all contribute to the typing experience, and all of these things mean different things to different people. Keep in mind that the reviews below represent my own opinions, and I tried to differentiate between things that personally appeal to me (clickiness, for example), and more objective characteristics (like build quality). The upshot is that there is no clear winner, and you will probably just need to try a few of these out to see which ones inspire you to get out of bed in the mornings and begin your day of typing.
If you know you want a mechanical keyboard and you're just here to see and hear about some different models, skip on down to the video reviews. But if you're wondering why in the world someone would buy a relative expensive mechanical keyboard when you can get a membrane or scissor-switch keyboard for far less (and sometimes for free), read on.
