I upgraded from the mac magic keyboard to a DAS about a year ago. It was well worth the investment. The crisp feel of the keys is so much nicer than the mushy mac, and I experience much less hand fatigue and wrist pain. I have the DAS 4 Professional. I went with the brown "tactile" switches rather than the blue "clicky" switches so that I wouldn't drive my family crazy, but even without the clicks it still has a very nice, precise response.
