There’s no doubt that a wireless mouse can be more comfortable to use than a wired one but when it comes to keyboards I don’t see the point of paying out extra money. It sits on the desk anyway so what is the advantage of a wireless keyboard? This wired keyboard from Logitech is my favourite model and you can order one for less than $20. If you do a lot of writing then you’ll appreciate the design.
It features a comfortable elevated wrist rest and the keys are laid out in a gently undulating pattern which matches your fingers. It is perfect for touch typists in particular. The keyboard also features a number of shortcut keys which allow you to zoom or skip to a specific folder. Having been unable to get used to the split keyboard style I found this keyboard was a happy compromise and much more comfortable to use than a basic flat model.
