This little phone strap is actually a USB cable, with a standard male connector on one end and a mini-USB male on the other. (The type normally used on phones.) Painfully clever—if you use a wrist strap on your gadgets. (I tend to not.)
It's $20 normally, but may be on sale from Wireless Ground for around $12. It appears to be sort of large, though. I'd like to see a company with a few more design chops take a crack at this, then start offering it as standard equipment.
