Dell recently announced the Mini 10 netbook at CES 2009 and since then many have been wondering what it will cost. That information may have been revealed by an unlikely source — a supermarket here in the UK.

Tesco has uploaded a product page for the Dell Inspiron Mini 10 and prices it at £349 (US$480). Whether it will price the same in the United States remains a mystery but at least we have some insight now into the sort of figure attached to this highly anticipated netbook.

The Mini 10 slots between Dell’s Mini 9 and Mini 12 models but stands alone impressively with some cool features. The most notable one is the 10-inch screen and its “edge to edge” 720p (1280×720) resolution with 16:9 aspect ratio for HD content. It also comes with a built-in TV tuner, integrated 3G WWAN/GPS, and multitouch support, in addition to the more common specs (1.6GHz Atom N270 CPU, 1GB of RAM, 160GB hard disk, etc.).
