The Moshi Concerti is a good choice if you're seeking something different to cover your iPad with.
Moshi's Concerti case for Apple's new iPad and iPad 2 is a popular item in CNET's San Francisco office, where it was passed around, lived with, and fought over at least once.
The $55 fold-over case has many charms, including a soft microfiber material and the ability to trigger the iPad's sleep/wake mode. The case keeps a strong grip on the iPad with a silicone sleeve, and has an elastic band to keep it more tightly bundled still.
The Concerti also has a couple of quirks that you can read all about in my full Moshi Concerti review.
