This is my very first keyboard with mechanical key switches. I have to say that, coming from a rubber dome keyboard, the sound and feel of the Model M is infinitely better quality. I agree that it's very similar to a typewriter.
This particular keyboard is the 1993 model, which I purchased at http://www.clickykeyboards.com/ Since the original Model M's are limited in stock, you should grab yours now before they all run out! Alternatively, you can buy a Customizer keyboard (the clone of the Model M's) at http://www.pckeyboard.com I hear they are almost, if not just, as good. Hope you enjoy the video :D
