A friend just picked up the Logitech Ultrathin Keyboard mini slim protective keyboard cover for his iPad mini, and I must say it is a nice and comfortable and sleek add-on for using apps, watching movies and viewing photos. With its seven-inch design, the cover offers full-size keys for typing, which worked better than I thought it would, but the $79.99 price is a bit high.
more details from Logitech:
Attaching securely with the click of powerful integrated magnets, the Logitech Ultrathin Keyboard mini has a slim aluminum cover that matches the iPad mini and brings durable protection to it with minimal weight. When you’re ready to use it, flip the Logitech Ultrathin Keyboard mini around to reveal its built-in Bluetooth® EasyType keyboard, offering a traditional typing layout in a small seven-inch form factor, plus iPad mini function shortcut keys for the commands you use most often, such as copy and paste. It also doubles as a hands-free view stand so you can use your iPad mini without having to hold it.
The Logitech Ultrathin Keyboard mini has an instant On/Off feature, which means your iPad mini automatically wakes up when you open the cover and switches to standby when you close it. The keyboard itself has a three-month battery life (based on usage of two hours per day) so you can spend more time exploring your new tablet and less time worrying about your keyboard losing power.
