I just realized what I am missing when travelling. It would be really good to have something the size and shape of a pen, whith a couple of click buttons on it that was a mouse. The laser would be at the nib, so I could write on any surface, the battery stored in the body of the pen, along with the USB dongle. Battery recharge could either be by a USB to 1/2USB on the pen end of kinetic from moving the pen. It wouldn't need to be a long life battery, just somehting I could tuck away and carry easily when I am working and using my laptop for business rather than playing games, carrying a mouse around is cumbersom, a pen in the pocket would be great.
