Along with its fast new processor and juggle-inducing weight reduction, the upcoming iPad Air brings a new form factor to Apple's tablet for the first time since the iPad 2 nearly three years ago.

However, this exciting change also means that users are going to need new accessories tailor-made to the new shape, and Logitech has answered that call with a slate of iPad Air keyboards and cases.

With Logitech products like the Ultrathin Keyboard Cover being some of the most popular iPad accessories, it was only a matter of time before it introduced an updated lineup. The company even teased its plans on Twitter the day of the iPad Air announcement event. Now, the four new products have been revealed.

The Logitech Ultrathin Keyboard Cover returns with the same combination of built-in Bluetooth keyboard, aluminum-backed screen cover, and $99.99 price point. However, the size and colors have been revamped to match the iPad Air's new aesthetic.

For $149.99, users can opt for the FabricSkin Keyboard Folio. The water-repellent case snaps onto the iPad using "SecureLock" and includes a keyboard grafted into its inner lining.

The $99.99 Ultrathin Keyboard Folio (right) also features SecureLock and can display the iPad at two different viewing angles: upright for typing and flat for browsing or viewing content.

Finally, the Folio Protective Case forgoes the keyboard but is the thinnest and lightest new full-size Logitech case for the thinnest and lightest new full-size iPad. At $49.99, it's also the cheapest.

The three keyboard cases reportedly get three months of battery life from a full, micro-USB charge. All of the new Logitech keyboards and cases are expected to launch alongside the iPad Air this November.
