Just a note about the Maroo cases versus the Evio Harmony. They're similar in design and price. It appears (from the photos of the Maroo) that it's somewhat thicker than the Harmony. i.e. more "padded." That may be a plus or a minus depending on the user's requirements.
As far as functional design is concerned, the Maroo may be superior in terms of the typing and viewing positions offered.
I'm still a fan of the Harmony's look and feel, especially given that it adds so little bulk to the iPad, but the Maroo cases have their advantages.
I have the Marware CEO "hybrid" case for my Kindle Fire. Assuming the quality is similar, it's a very nice case. Interestingly, the iPad case is considerably less expensive than the case for the KF.
