Great review - I've missed these
Maybe people today don't realise you can adjust the mouse tracking speed, thus their mouse pointers move really slowly, and they need to move the mouse much further across the desk to cover the same distance of the mouse pointer moving across the screen. I always put my mouse's tracking speed to maximum.
The main reason why I don't use my SSKs (one IBM and one Lexmark) is the absence of a Win key - making this Unicomp keyboard very tempting.
