iPad Air Keyboard - ZAGGKeys Folio
Apple doesn't sell an iPad Air keyboard, but there are options for users who need mobile productivity. The ZAGGKeys Folio is an iPad Air keyboard case that includes a backlit keyboard and full protection.
The keyboard connects to the iPad Air over Bluetooth and is available in white and black. Zagg promises 3 months of battery life with two hours of use a day. The Gotta Be Mobile team are big fans of Zagg Keyboards for the iPad and iPad mini, and this looks like another winner.
