Sandisk MicroMate is a lovely little thing I may never have found out about if I hadn't gotten one once in a bundle with a memory card. It's simply an SD-card reader with no cable, the USB plug is right on it. Which means it's not much bigger than an SD card. Cheap and handy for getting your pictures or data into your computer. You just take the SD card out of the camera and stick it in the MicroMate (it has a slot at the bottom), then plug the micro-mate in the computer’s USB port.
(With an empty SD card in it, this thing can also be used like a "thumb drive", to transfer information between computer, or to put confidential data on away from the computer, etc.)
Given a free USB port, you may even just let it sit in the machine (if it's not moved around much), no unsightly cables to lie around on the table top.
