Dell, one of the world's top ranked laptop manufacturers, has introduced to the UK market a pair of new laptops which are reportedly upgraded versions of its Z Series of Inspiron laptops. The new machines, being marketed as the 13z and 15z, have come right after the 11z, and are much thinner coming in at 26.4mm and 29.2mm respectively.

Both the new offerings are equipped with the latest Microsoft Windows 7 operating system, a webcam of 1.3 megapixel, in-built Wi-Fi and a 320GB hard drive. In addition, they are fitted with a low voltage processor which ensures a long battery life of up-to 10 hours.

The new range of Dell laptops are now on sale at the company's official UK website and, like all other models, can be customized by the buyers. While the Inspiron 13z is priced at ?479, the 15z is available for ?499. The prices are inclusive of shipping and taxes.
