After weeks of teaser campaigns, leaked photos and specs, Dell has gone official with its slimline laptop offering that it hopes will offer an alternative to the Sony X Series, Apple MacBook Air, and Samsung's X series as well.

The new model, which averages at 9.9mm thick will feature a new innovative hinge design that sees the keyboard fit into the screen area so save space.

Specs include a 13.4-inch HD WLED screen, Intel Core 2 Duo ULV 1.4GHz processor, 4GB memory, 128GB SSD, wireless n and Bluetooth connectivity and DisplayPort, 2 USB ports and a headphone jack. The laptop will not feature an Ethernet port, or optical disk drive.

The new model will cost $1799 and should be here in time for Christmas.
