A dual screen computer which allows punters multi-task while on the move has been shown off.

The Spacebook, is being flogged by the Alaska-based technology firm gScreen and apparently it answers the need in the financial industries to run two screens at the same time while working on the train. Of course it is not clear if fellow passengers will be happy with you and your screens taking up most of the room on the seat.

The gScreen Spacebook will boast two 15.4 in screens which can slide away to fill the space of a single screen when the laptop is being stored or transported. Gordon Stewart, the founder of gScreen, said that Spacebooks should be available on Amazon by December this year, once final modifications are complete.

It looks like the gScreen will cost £1,835 but you are going to need to be a bit stronger to carry it. Running two monitors will also prove a drain on the computer's batteries.
