hawkfanz, the BoxWave miniSync we're talking about does NOT charge through the USB port. Check the supplied link, and you'll see that aside from the cool retracting form factor, it's equivalent to the Nokia supplied USB-to-miniUSB cable (which doesn't charge the N800 either), with the addition of an extra 5" cable section leading from the miniUSB to a 2mm (approx.) Nokia power tip. That's how they route the juice from your USB power source (wall wart or powered USB port) to the N800's standard power jack. So at least in theory, the cable does double duty: data connection through the miniUSB, and power through the round tip.
