When I got this iPad last March I unpacked it, fondled the smooth surfaces for a short while, and realized that I would have to get a non-smooth case or I would be dropping it all the time. I bought a super cheap folio case that could also be used to prop up the iPad in landscape mode. It served well, but is looking a little battered. One of the iPad web sites recommended Moko as making affordable smart cases so I checked it out.
The MoKo Rotating Detachable iPad Cover (above in landscape prop mode) is a smart case, which means that it turns off the iPad when I close the case. It also rotates so that I can prop up the iPad in portrait mode. I ordered it last week from Amazon, after reading the reviews there, and I am very pleased with it.
