Another fun photo accessory is the Merax Mini USB Strap -- it's a wrist strap with integrated Mini-USB cable, for around $10.
The strap is the thin plastic USB cable, which loops to a length of around 5 1/2 inches (a tad small for a big hand). The strap loops through a small plastic box that protects the connectors.
Then to use the cable, slide off the plastic end, and pop out the two connectors -- USB to mini-USB (it takes a little dexterity to wiggle them out). Then extend the cable to about 12 inches.
That's it -- Now you can carry a USB cable along with your camera (or other portable device), disguised as the wrist strap.
