Yeah, ever since I started using my own keyboard at work I've had a dedicated one for the purpose. Who wants to carry a keyboard with them wherever they go?
When I first started with mechanical keyboards 15 years ago, I first bought a Model M for home, but continued using the work issued rubber dome at work. Then when I upgraded my home keyboard (a black Model M13 Trackpoint II) I brought the old Model M to work.
I had an office at the time, so I didn't have to worry about having a noisy keyboard.
A couple of years later there was a ceiling leak at work, and that Model M never worked right again
Since then I have been using work issued rubber dome keyboards at work. I wanted to get another mechanical board, but I was always worried about the noise, until last week.
I ordered a first gen Ducky One with MX Clear (tactile, no click) switches, and a set of o-rings to install and make it as quiet as possible. It won't be silent, but I'm hoping it won't be any louder than the Logitech rubber dome one I have now.
If I am on the fence regarding if it is quiet enough, I'll probably send an email to everyone in my work area with a link to an anonymous SurveyMonkey or something like that, so they can tell me whether or not it bothers them without any worry about being antagonistic.
Tactile Clears with o-rings are likely to not be that thrilling for me, coming from buckling spring, but it should definitely be better than this mushy Logitech junk.
