My Microsoft Bluetooth wireless Intellimouse doesn't have a power=20
switch and the batteries (2x "AA") seems to last a couple of years.

My Logitech Laser V470 mice *do* have power switches but the=20
batteries also seem to last a really long time.

With both mice, I have to shake the mouse if it has been sitting idle=20
before the mouse pointer starts to move.  I'm used to it and it=20
doesn't bother me.
