While here in the UK, Dell's not-a-netbook the Inspiron 11z has gone on sale direct recently, in the States the company launched the 14z and 15z in September.

For reasons best known to Dell's execs, in the UK it's just been announced that the range is to be expanded with the 15.6-inch 15z, and instead of the 14z, the 13.3-inch 13z.

Measuring in at 26.4mm thin for the 13z and 29.2mm for the 15z, both laptops feature the new Intel CULV ultra-low-voltage processor and come with Windows 7 pre-loaded.

With an HD display as standard both offer Wi-Fi, HDMI, a 1.3-megapixel webcam, hard drive of up to 320GB, up to 6GB RAM and the boast of battery life of over 10 hours.  

The Inspiron 13z and 15z are available in "Obisidan Black" and "Cherry Red" with the Inspiron 13z priced from £479 and the 15z available from £499.
