A word of caution... The unit found here from Boxwave: http://www.boxwave.com/products/mini...a-e62_2097.htm does not fit the Nokia N800 quite right... It's a bit too small (as has been stated previously in these forums, it wasn't a fluke...). It's very finicky about staying connected and charging if you ever so slightly move the N800. I'm in the process of returning mine now . The concept is perfect though. I wish I could find another unit that is retractable and supports USB and power like the Boxwave product.
