Those of you who've used cordless mice will appreciate the freedom of movement they afford and the lack of a cable that snags and drags across your desktop. Unfortunately, cordless mice are not without their downside, namely relatively poor performance compared to an equivalent corded mouse. Some cordless mice I have previously reviewed can be seen
here and
here.
Let's not forget the other big disadvantage, the fact they require batteries! In fact this is the main cause for their poor performance. In an attempt to maximise the battery life, the mouse's optical detection system is operated at a lower power level than those normally used in corded mice. This results in reduced sensitivity and poor tracking. Another problem, again related to a degree to battery power conservation, is the radio technology used to communicate between the mouse and the computer only relaying mouse movements at a lowly 25 - 50 updates per second. Resulting in a jerky and imprecise on-screen cursor movement. A typical USB corded mouse has an update rate of 125 times per second, producing a significantly smoother and precise movement, not to mention cheaper. It is easy to see why cordless mice have never been as popular as their corded brethren.
Apparently that is until now...
