Mice eat batteries because they have to stay awake longer. A KB only wakes
up when you press a key. The mouse has to watch for motion at all times, so
it needs to have its LED on. Most mice time out after a bit (a few minutes?=
)
and turn off the LED. At that point you have to click a button to wake the
mouse up again. Most mice do *not* pass that wake-me-up button click to the
host.
