Do you ever get tired of hearing the sound of yourself typing? Honestly, it's never really bothered me, but I'm sure that if you work near other people, they might get annoyed with it after some time. Next time you go shopping for a new keyboard, you might look for one that's a bit quieter than the rest. Take this one from Thanko which is not only silent, but works on two PCs.
While it's pretty obvious what it means for a keyboard to be silent, I don't often hear of one that boasts the ability to work on two computers at the same time. I guess that it's really not the same time, but a flip of a switch just above your arrow keys will allow you to operate on a second computer.
