Review: Mio DigiWalker C230 GPS Navigation - The Gadgeteer
The Gadgeteer have published a review of the Mio DigiWalker C230 GPS portable navigator. 'Overall, the hardware is really very nice. The touch screen is quite responsive and doesn't smudge too easily. The unit feels sturdy. The battery lasts around four hours, and takes awhile to charge if it's powered up and running while charging. However, I imagine the battery life is similar for any GPS - having to maintain a constant satellite connection uses a lot of power, no matter what you do. I really like that it charges via USB (most brands of GPSes I've seen do), since it means that it can be hooked up to a computer without any special cables.'
