I would recommend against silencing your keyboard unless you use it in a room with other people (public office, etc.).
I guess but I think there are many other reasons (other than just personal taste of liking the sound of silenced sliders of course).
My two, and why I plan to silence:
1) At home, my current office area is near some other public areas in the house. Just trying to be considerate.
2) At work, I have my own office with a door that I can shut but I also get on conference calls. Need to silence for stealth, secret typing.
That said, I am curious. You said, "[you] would recommend against it". Is there something else I am not thinking of?
