sorry to drag this back up...but with Christmas not far away the missus has started shopping.
i've suggested this to her for me
http://www.amazon.co.uk/APC-Back-Power-Saving-Outlet/dp/B002RXED6A/ref=dp_cp_ob_computers_title_1
it has a usb data control line, anyone know if the dns-320 would recognise it?
