Even though the Apple Inc. has issued no keyboards for iPad or iPad 2, there’re actually many companies designing and launching wireless keyboards for iPad users. The Levitatr Keyboard is just one among them. It is merely 12mm high, with a smooth black surface when not in use. But once you switch it on, its keys then raise out and the backlighting turns on. Currently it’s a Kickstarter project, so we can only check out the video now to see how it works.
