If I were to work on an office for a long period, I would need at least 2 monitors and a very good keyboard. That’s the most important to me.
I see way too often offices filled with keyboards that were found in some unknown dark places and they are just a pain to use. If you are going to type 8 hours a day on a computer, a good keyboard is a must, and yet I don’t see them often enough.
I’m not sure what you mean by “unsolved” however, could you explain more on that?
