Lenovo is targeting designers who need a large, accurate screen, and will also benefit from an in-built graphics tablet, with its latest laptop.

The ThinkPad W700 has a whooping 17 inch screen and, perfect for designers who use CAD and photography editing packages, the laptop comes with a digital tablet built-in so you can use the stylus to manipulate your work.

Also worth a mention are the new Nvidia Quadro FX 2700M and 3700M Open GL graphics processors with up to 1GB of dedicated video memory.

And there's also support for the upcoming Intel mobile quad core processor.

Other features include optional dual hard drives with RAID configurations, up to 8GB of high speed DDR3 memory, a range of wireless connectivity options and multimedia capabilities including an optional Blu-ray DVD burner/player.

"Lenovo has engineered a new breed of mobile workstation with the ThinkPad W700," says Peter Hortensius, senior vice president, Notebook Business Unit, Lenovo.

"The ThinkPad W700 mobile workstation flat out delivers the command performance our customers demand at the desk as well as in the field."

The mobile workstation includes Wi-Fi wireless connectivity as well as optional Bluetooth.

Models supporting WiMAX will be available later this year.

The new model's optional 400-nit WUXGA display provides "up to twice the brightness of earlier ThinkPad mobile workstation models", and the 72 percent wide colour gamut provides more than 50 percent greater color intensity.

For external connectivity, the ThinkPad W700 mobile workstation provides support for Dual Link DVI, Display Port and VGA, as well as offering a 7-in-1 multicard reader, and five USB ports.

Packed for extreme performance, the mobile workstation also features BIOS/port disablement and an optional fingerprint reader, a smartcard reader and hard drives with full-disk encryption.

The ThinkPad W700 mobile workstation will be available from September with models starting at $2978.
