There are 2 methods of achieving a cordless connection. Infrared and RF. The Acer uses Infrared, line of site, which means the transmitter (keyboard) must be pointed at the receiver. I have one, and it bites. Speed is often reduced with this method. The Logitech uses RF, and works like a radio transmitter and receiver with antennas, only at very short range. Doesn't matter where you point the transmitter (keyboard), as long as it's within the range. Much faster than infrared, and speed is equal to regular corded keyboard. I have the cordless desktop, which includes a cordless mouse. No drivers or software are needed for it to function correctly. Once you try the Logitech cordless, you will never go back to a corded system. Fantastic product.
