More on Clicky Keyboards, a response to Pablog’s comment
For full context, the Das Keyboard isn’t the only keyboard I’m looking at. The two other models are the Tactile Pro 3 and the Quiet Pro  by Matias. So far, though, the Das is the only model I can find to play around with at NYC stores. I may have been given a good lead on a location that may have a great selection of third party apple products, so this may be updated later.
The Das Keyboad and the Tactile Pro series are known for - amongst other things - not fading into the background of your writing environment. They are not thin, they are not quiet, and they are not light. And yes, as Pablo noted, they are built to click. To click loudly, even. They are so known for the noises made that popular mac blogger Shawn Blanc’s review of a few different models is simple titled Clicky Keyboards.
For me, the noise level isn’t what’s drawing me to these keyboards. It’s that I don’t like the feels of the clicks on my current keyboards. The keys on the keyboards I’ve mentioned above are jumping up and down via mechanical switches, and not the plastic scissor switches with plastic membranes that the chiclet keys on all Apple keyboards today use.
These key switches provide a drastically different experience, giving feedback to the typist and supposedly leading to a better typing experience. What I experienced typing (rap lyrics and short reviews of podcasts) yesterday at TekServe, was - physically - the closest thing the modern computer user can get to using a typewriter. If you look at the above image, the blue/brown switches of the keys push down and the springs help provide the feedback.
Of course, though, the clicky nature of the keyboards is something that has to be helping and hurting the experience of writing. Helping, because of the auditory confirmation of keys being correctly clicked, and hurting because it’s driving you to be an even bigger hermit than you were before already, since these things can’t be easy to be around. Well, I guess that’s only a problem if your writing is taking place in an office or during your off hours when those who live with you are around.
But some swear by the loud keyboard lifestyle. Whatever works, though, is the old phrase about writing. If you’ve found a working solution (and I quickly banged this out on my laptop’s keyboard, so who knows what I really need) you might not need to jump onto the good ship Mechanical Switches. But if you’re like Pablo, and you write for a living, there is an allure in getting into the clicky keyboard game. It just can seem like a cult depending on how far away you’re examining it.
For further information:
Shawn Blanc’s Clicky Keyboards is a good entry point to the conversation, and for further down the rabbit hole, Overclock.net’s forum section on mechanical keyboards is almost too informative and detailed.
 The Quiet Pro, though, is a recent release from Matias and delivers a less clicky experience, but all reports are saying the keys are noticeably lesser in terms of the clicking experience for feedback, etc.. If I get a keyboard, it will likely be one of the two loud models, if only because I do care about the feel of the keys.
