If you try to work from an iPad exclusively, it can be done but you will not want to do that with the onscreen keyboard for an extended period. Thankfully, the iPad supports Bluetooth keyboards and you can connect an external keyboard to the iPad and work all you want in comfort. The iPhone and iPod touch also support a BT keyboard in later models.
Photography shop Adorama has been rolling out all sorts of new products into its catalog for a long time and it has a wide range of gear that has nothing to go with cameras today. The latest new item from the company is a BT keyboard called the iBoard Bluetooth Wireless Keyboard. The iBoard supports the iPad, iPhone, and iPod touch and has some dedicated keys to access sites with one button press.
The keyboard is controlled by an app that gives shortcuts to the favorite apps on the device and the favorite websites of the user. The Flashpoint iBoard kit sells for $69.99 and has the same specs as the original Apple wireless Bluetooth Keyboard with the addition of the single key shortcuts. The app is on the App Store right now at no charge. The kit also includes a free iBoard waterproof skin to protect the keyboard from spills.
