I was recently looking at my mouse on my laptop and i moved it to my other laptop then had to move my thumb drive with my files over and i thought to myself that it would be cool if my mouse had a couple of micro sd card slots on the bottom or edge of it somewhere that i could expand the memory and one less device to worry with. 
there should be plenty of room in it and if it is wireless maybe modifying the usb dongle to have the memory in it instead. to many possibilities.. is this a possibility of a build?
