I really like modular design solutions, so this HotSync and charger cable suite caught my eye. At the center of the system is a small, light USB HotSync cable for traveling. However, when you add the optional AC wall and DC car charger adapters (which connect directly to the USB end of the HotSync cable) you can also charge your PDA at home, in the office or in a car. This makes for a perfect travel system, since it's much smaller, lighter and more flexible than my OEM cradle and charger cable... and it works in the car.
I found the cable, AC wall and DC car adapters that work with my Clie N610C at Proporta, however my father located a similar suite for his N710C at CompUSA, so I suspect these can be found in many places if you look for them.
