Probably a good 3 years

I love that click click click noise..
I guess now, there is some software that can decipher your typing noise and make it into something readable.. crazy shit

I always buy an old keyboard when I break mine. Need to clean it, on these old ones, throw them in the dishwasher without heat. No problem. Let it dry in forced air, real well, before you plug it in again.

Down at this computer store here this guy has 200 computer keyboards we couldn't get $50 for. I live in a waste-land. If anyone wants them, let me know.

Couple of years

Hubby came home from work last night with a new keyboard for me. Some women like flowers...

I have Logitech MX3000 set for about 2 years and it's still very good...
If I could find a new one in stores I'd replace it with same set, since I really got used to it...

Couple of years...

Couple of years for me. I spray disinfectant on the keys for hygeine purposes but eventually they get grotty... I buy a new one rather than clean it.

I get a new keyboard when I get a new PC which is usually every 2.5-3 years. I've never needed to go out and buy a keyboard.

3 - 4 years

A year or so...

usually i have problems with the mouse .. and i change the keyboard in same time , around 1-2 years
