I've thought for some time now that something like two iPads that can work together as a single computer with a 180 degree hinge in the middle could be a very effective computer. One could be an extended keyboard, or they could work together to be an extended display, or you could fold one back and use the other exclusively.<p>Seems like Lenovo may have had the same idea, only with a different OS.<p>I'd still like to try the idea with a pair of iPads, although I realize that would also require some pretty deep custom software at the OS level.
