So when I saw the new “ Microsoft Natural Ergonomic Desktop 7000” few months back it seemed to fit my bill – came with a small USB Dongle as a base station and had ergonomic styling. I am particular about ergonomics and I prefer keyboards that have a natural curve for hand comfort with a good play of the keyboard buttons as I type pretty fast.
Most of the wireless models anyway have wires for their base station and you need to keep the base station almost touching the keyboard for any good signal reception. I see only one advantage of a wireless over the wired models is the convenience of giving it to the person on the other side of the table for a quick demo.
Over the years I have tried with little success various models of Wireless input devices (Keyboard and Mouse), right from the early Logitech desktop sets.
