I've got one of those retractable sync/charge cables (from Brando), it's great, keeps things tidy, allows me to connect my Z to my linux workstation at work to charge it up and SSH in.
Sharp provided a USB cable but it doesn't provide power. Why not? Is there a reason why USB shouldn't be used (apart from the power loading on the computer)? Can I convert a Sharp usb cable to also be a charge one?
