I have a “magic trackpad” from apple on a side table to use when I'm watching or reading something and recline too much to reach the mouse.

It's nice (and with some free driver I found can do multi touch on windows), but for some reason it had a battery (despite having a fixed usb cable) which pillowed up making it unusable until I literally ripped it off (damn thing had more glue than battery).

Obviously works fine without the battery, which I assume is just an attempt at extremely inefficient planned obsolescence, but I wouldn't recommend it, too much of a fire hazard if you don't notice the trap.

At least you know wired mice won't blow your hand up, and I value that more than the convenience.
