A friend (customer) has a Das. He loves it. Of course he had gone thru 3 Logitech wireless keybds, and his mom had used up one. So, to him, the Das is great. My wife tried it for a week (she used be a 130 wpm typist) and gave it a thumbs up. Her regular keybd is a Model M Space Saver, as is mine. I have to use it when I go to his house to work on something, and I find it to be OK, but a Model M it ain't. Totally different feel.
