Using a laptop has distinct advantages over desktops, most prominently in the mobility department. To gain that boost in portability, though, sacrifices must be made. As a whole, laptops lack the computing muscle offered by their clunky counterparts. That shows in more areas than one - not least in precious screen real estate.

Acknowledging this, a little-known company named gScreen has earned a seat in the limelight with its dual-display-packing notebook. Called "Spacebook," gScreen is working on models that house two 13, 15.4, 16, or 17-inch LED-backlit LCD displays. With a specifically tailored sliding mechanism, the Spacebook's secondary display can be slipped out when needed, and tucked away when not.

In an interview with Gizmodo, gScreen said the Spacebook's specifications will include an Intel Core 2 Duo, 4GB of RAM, an Nvidia GeForce GF900M, a 7200RPM HDD, DVD drive, six or nine-cell battery and Windows 7. The company's website has more details, listing a Core 2 Duo P8400, 4GB DDR2 RAM, 320GB 7200RPM HDD, 512MB Nvidia GeForce 9800M GT or Quadro FX 1700M, and VGA/HDMI-out.

Given the slightly dated specifications, I assume the Spacebook's hardware will be revamped in the models to come. As attractive as a laptop with two displays may be, the complete package probably weighs in excess of 12lbs, not to mention the elevated power consumption. Just something to keep in mind before you plunk down your hard earned dollars.

The company is pressing for December 2009 launch -- probably to snag a few holiday sales -- and plans to have the first units sold via Amazon. Although there is no official price established, gScreen is reportedly trying to keep it below $3,000.
