Zagg ZaggKeys Folio for iPad Air
This cover is the priciest of the lot reviewed here, but it ticks every box on the list of what you would want from an iPad Air keyboard case.
This folio case has a Bluetooth keyboard cover and a plastic back case, which protects both the front and back of your iPad Air. Its smooth exterior is made of faux leather but allows for a good grip.
When the cover is closed, the device is only 17.7mm thick. The connecting hinge allows you to adjust the viewing angle incrementally all the way to 135 degrees.
The full-sized keyboard means you do not need to relearn any new key positions. I hardly made a typo when using it.
The keyboard has an additional top row of Function keys - a dedicated Home button, Lock Button, Siri and volume controls. Usually, such functions require you to hold down a Function key and one other key.
Furthermore, the keyboard is backlit, which makes it great to use when you are on a long-haul flight and the plane cabin is in sleep mode. There is a dedicated button to activate the backlight and you can even change the light's colour.
The cover's major downside is that it is rather heavy at 535g. Add the iPad Air and the whole combo tips it over the 1kg mark.
Also, this keyboard works with the tablet only in landscape orientation.
Despite these slight drawbacks, this is the best iPad Air keyboard case on the market.
Moshi VersaKeyboard for iPad Air
A major downside of owning an iPad keyboard case is that you may lose a foldable cover. But the Moshi VersaKeyboard offers a great solution.
It has an origami-inspired foldable front cover which supports the iPad Air's auto-wake and sleep functions. On its plastic back is a slot for you to store the detachable Bluetooth keyboard. So you get the best of both words.
Insert your iPad Air into the back case, and you can fold the front cover back to read an e-Book. You can also place your tablet in either portrait or landscape orientation using the foldable cover.
When you need to do some word processing, just slide out the keyboard and type away.
The detachable keyboard is slightly smaller than most iPad Air keyboards. However, the keys are well laid out. Additional iOS controls, such as volume and cut and paste, are combined with the number keys and activated using the Function button.
Overall, I made few errors typing on the keyboard. But its tactile response is lacking and the experience feels rather flat.
The VersaKeyboard adds 380g of carrying weight and doubles the thickness of your iPad Air. But the overall weight is still under 860g, which you can easily lug around.
If you do not mind the lack of a tactile response and having to slide out a keyboard, this is close to an ideal case for the iPad Air.
