You do realize the iPad is already foldable and there is even a youtube video of the guy on "Will it Blend" folding it so it will fit in his blender. Of course as was already mentioned in this thread, this would void your warranty. 
I like that iSpine concept but I think the iPad is the first serious attempt to liberate us from the awful "L shaped" computer. I don't mind having an accessory that turns my iPad into a netbook for an hour or two at a time such as the clamshell case or an Apple BT keyboard along with a plate holder, but if I wanted an L shaped iThing, I think I would go for a Macbook Air.
