That is precisely what I use! It's wonderful, and the only thing that could make it better is if someone came up with a cable that had a mini USB-A connector (for the n800/n810) on one end and a female A connector like the linked item has, for a direct connection. I'm quite tempted to hack a USB extension cable to replace the full size female A with a mini-male-A and add a small jack in the middle of the cable to provide 5V to power-hungry devices. I have a PSP on-the-go charger that can power something as power-intensive as a USB 30GB hard drive to plug into the connector. I'll post pictures if I get around to it.
