Asus has launched an ultra-portable high-definition multimedia laptop featuring Blu-ray technology.

The Asus M70 packs a 1TB hard drive, which the firm claims can store over 350 full length movies.

A 17in high-definition screen responds to ambient lighting to deliver "the best possible experience" and avoid eye strain, according to Asus.

The Widescreen Ultra eXtended Graphics Array has an enhanced Full-HD definition of 2.3 million pixels at 1,920 x 1,200 resolution.

Sound is delivered by four built-in Altec Lansing speakers and a subwoofer, and a dual-mode multimedia interface touchpad doubles as the tracker pad.

Powering the unit is 4Gb of memory and an Intel Core 2 Duo T9300 at 2.5GHz.

The laptop comes with a Blu-ray copy of Batman Begins but there is no word yet on pricing.
