You mean you still use a keyboard in this day and age of the touch screen
I am still using not just any old keyboard, but a classic IBM AT keyboard that is at least 20 years old. At that age it does not have a "Windows" key of course
I have about 6 of these keyboards in store. They were thrown out at work when we replaced IBM PS/2 machines with something newer. I cannot understand why everyone except me allowed their AT keyboard to be taken away and replaced by one clearly inferior. - you would think that engineers would know better (ditto the Microsoft mice replaced by dirt-cheap tat). I kept mine, and rescued half a dozen from the skip for good measure. They are pieces of engineering and will last for ever (or until mobo's no longer provide the PS/2 connector). They are superb - although old and used, they now fetch anything up to £100 on ebay.

I have seen them severely criticised as "heavy". So what? It sits on a desk all the time, I do not carry it around.
Another advantage is that the connecting cable can unplug from the keyboard. I have two pc's under my desk with a cable from each. I can just swap plugs to access either PC with the same keyboard.
