Hard to say what's going on exactly what this clusterfrack of a listing over at Tesco. While the Dell laptop shown is the £299 Inspiron Mini 9, it's labeled with an Inspiron Z530 title bellowing a 12-inch display. Moving down to the specs, we've got a spec-for-spec match to the unreleased 12.1-inch E Slim exclusive we brought you back in June: same 1.6GHz Atom processor; heavier 1.2kg (2.6-pounds) weight; bigger 12-inch WXGA (1,366 x 768 pixel) display; wider 29.9-cm (11.8-inch) dimension; and 40GB hard drive spinning
P.S. Dell doesn't sell a Atom-based 12-inch laptop under any model number presently, nor does it have a Z530 in its product roster.
