The benefits of compact
Ergoapt: a compact wireless, ergonomic keyboard with full sized keys, scissor switch motion, low profile aluminium case and rechargeable battery.
The difference between a full featured keyboard and a compact keyboard is that the compact keyboard does not have a numeric keypad.
This makes compact keyboards narrower, reducing the distance and reach required to the mouse.
The compact size allows for a more relaxed, natural and centered working position.
Reducing movement outside of the core working position by not reaching for the mouse whilst working helps reduce RSI issues from occurring.
