The ClamCase looks like a sleek netbook when closed. It's also about the size and weight of a netbook, adding 1.6 pounds to the 1.44 pounds of the iPad, bringing the whole package in at just over 3 pounds.

Most require you to slide the bottom edge of the into a slot directly behind the keyboard to prop it up in typing mode. Since the ClamCase relies on a sturdy hinge to keep the iPad at the proper angle, you don't have to reposition the iPad when you open the case.

Many cases give you only a single groove to fit the iPad into, providing just one viewing angle for the screen. ClamCase's unique double hinge gives you every angle, from closed to flat on the table. It even keeps going around the back, so you can fold it completely inside out to hold the tablet up with the keyboard behind it.

The other thing you get with the ClamCase--something that you don't see in cover- or folio-style cases--is a wrist rest. Because the iPad sits at the very back of the case, there's room for a genuine wrist rest in front of the keyboard. It looks like it should have a touchpad in the middle, but that wouldn't accomplish much since the iPad doesn't support cursor navigation on screen.

Unfortunately, this setup has one major drawback: It's top-heavy. On a table, at my preferred angle, it was no problem; when I used it on my lap, I had to keep my hands down on the wrist rest, or the entire thing--iPad and all--would tip backward.
