It's big. It's loud. It's expensive. (Did we mention that it's loud?) And if you want the tactile experience of an old-school keyboard (think the classic IBM Model M), the Das Keyboard Model S Pro may be as good as it gets. In addition to the expected mechanical-switch keys, this one adds some modern features, including media-control keys and dual USB ports. Just be prepared to keep your office door closed at all times, or to deal with banishment if you work in a cube.
