Logitech has introduced two new fully protective slim keyboard folio cases designed for the iPad Air - the $150 FabricSkin Keyboard Folio featuring a slim design with a seamless fabric-covered and durable water-repellant Bluetooth keyboard integration with a "wipe-clean" surface similar to that of Surface Touch Cover, as well as the $100 Ultrathin Keyboard Folio which is essentially an identical folio cover but features a different Bluetooth keyboard design that isn't water-resistant and has individually laid out keys. It's also marginally thicker than the FabricSkin's built-in keyboard as a result.
