Berlin's Weltunit has created what may be the most ingenious tablet/smartphone prop around in the form of the Cardboard iDevice Stand. This stand is made using laser-cut cardboard and is designed to have a lifespan as long as your gadget's.
It seems like a new iPad/iPhone is released every year, which makes buying a stand that works for a specific model a waste of money. It is also an environmental burden to buy tech accessories which will soon be outdated. That's what makes the Cardboard iDevice Stand so awesome. This stand is compatible with the iPad2 and iPhone (3GS to 4S). When you are ready to upgrade your iDevice, simply toss Weltunit's stand in the recycling bin. The release of this stand is kept mysterious (you must sign up for Weltunit's newsletter for release dates), but you could always try and make your own Cardboard iDevice Stand.
