The microfiber-lined plastic shell magnetically opens up, and a small plastic stand clicks between both halves, forming a sturdy tabletop stand for portrait or landscape mode, with either the iPad or iPad 2. The stand's roomy enough to accommodate some back shells we've used. A slide-out tray gives the iPad extra tilt, which was fantastic for at-the-desk writing with the keyboard in our laps. In normal stand mode, my iPad 2 was elevated like a picture frame. In the extended-out stand mode, the iPad viewing angle changes to nearly 45 degrees.
Across the top number keys are a set of iPad-specific functions, activated by holding down Fn on the lower left and pressing. The 5 key doubles as a picture-gallery shortcut; the 7, 8, and 9 keys alternately rewind, play/pause, and fast-forward music tracks; volume controls are on the end. These basic functions mirror what's on other iPad keyboards, including Apple's. A search button is tucked away to the right of the Option key, and it launches Spotlight search. Alas, you can't keyboard-click searched-for apps and documents--you'll have to tap on the screen. A Home key on the top right works like the one on the iPad.
You could also use the Logitech keyboard with an iPhone, if you so choose; iOS 4.3 supports keyboards, and we were able to use it on our iPhone 4 without a hitch. Music and volume controls worked, too. You could even rest your iPhone on the elevated stand. It's an odd pairing, but doable.
Logitech's keyboard is high-quality, too. We used it to write this review, in fact. It feels great, with every key being where it should. The direction-arrow keys also enable zipping through docs without reaching up to touch the screen when making line edits. That's the difference in our opinion between a keyboard case and a full keyboard like this one: writing on a full keyboard makes the experience feel nearly indistinguishable from sitting at a computer.
