It’s hard to make a keyboard that provides both tactile feedback and which is super thin… so some folks don’t even try. The Microsoft Surface Touch Cover, for instance, is a keyboard without moving keys. You just touch the surface to type. That makes it thinner than a typical keyboard cover for a tablet.
But it’s still a behemoth compared with the new keyboard CSR is showing off at the IFA trade show in Berlin.
The Microsoft Surface Touch Cover measures 3.25mm thick. CSR’s keyboard is just 0.5mm thick — although to be fair, it’s just a keyboard prototype, not a protective case.
Still, the company says its flexible Bluetooth keyboard is the thinnest around, offering a compact way to add a keyboard to a tablet, phone, or other device. Since the entire surface is touch-sensitive, you can also use it as a wireless touchpad for a notebook or desktop PC.
The keyboard is compatible with iOS, Android, OS X, and Windows 8.
