Paul over at Modaco http://www.modaco.com/index.php?showtopic=235176 spotted this very useful Key Ring
It's essentially a USB to Mini USB device on a key chain so you can charge and sync your device wherever there is a Computer with a USB port! No need to carry cables anywhere!
You can buy them here for $5 each! http://usb.brando.com.hk/mini5pinkeychain.php
I've just ordered a load!
