If you’re not familiar with it, Das Keyboard is the keyboard with two distinct features: it has a distinctive (and addictive) clicky noise, and it’s available with all the keys completely blank. There’s nothing less user-friendly, but there’s also nothing more monolithic and impressive. I’ve been using one on and off for a few weeks and you really get used to the click noise; it sets a rhythm and the keyboard itself is comfortable to type on. It has USB ports but doesn’t require any drivers, which is nice (my computer is a driver jungle). It’s a bit dear at $129 (it’s kind of a “boss” keyboard) but at least you get free shipping.
