Just added a Das Keyboard Professional S Slient to my setup. Finally i can join the "Mechanical Keyboard Club"!
And i have to say, it types sooooo well. When i unpacked it and typed the first words, it felt a little bit awkward, due to me being used to the very heavy Cherry G83 key stroke. But now after some minutes and a couple of more lines, i can't imagine ever going back to a rubber dome (at least for typing). I probably would have preferred the Blue Switches from the non-silent version, but noise is a factor, so i have to settle for the Browns (even they are borderline from the noise).
I really have to force myself to stop typing this post, it's that much fun!
