Yeah, I have 2 DAS keyboards as well. Got em a few years back and they are so much better to type on. Mine have no letters on the keys so people that can't type don't just come to my desk and "Hop on my machine"
The point is, don't just buy a Das keyboard to hop on the bandwagon. They do have disadvantages.
Most people are intimidated by the absense of labels, but my daughter takes it as a challenge and does pretty well without them.
