Dell has launched a range of tough notebooks aimed at government and enterprise users who often work in harsh environments, such as high altitudes or inclement weather.

The Latitude XFR range will feature more durable solid-state hard drives and outdoor readable screens, along with shock protection hardware and a new thermal management system.

The XFR D630 also sports a magnesium case and splash-proof keyboard designed for use in the rain and snow.

The durability comes at a price, however, and the new notebooks start at $3,899.

The XFR range was designed to integrate with other machines in Dell's business laptop branch, and will be compatible with the components and images of all other Dell latitude notebook models.

The company is hoping to pit the XFR D360 against Panasonic's Toughbook line, claiming that the new model performs 23 per cent faster than the competing Toughbook models.

Brett McAnally, director of Dell's product group, said: "We are taking a multi-dimensional approach that focuses on simplified deployment, service and durability without sacrificing performance. Major competitors focus their efforts on 'rugged' only."
