I recently had the opportunity to review a case for my Galaxy Tab 2 7.0. It's a simple, black book-like case with an elastic strap to keep it closed. On the inside left is 3 slots to use as a stand for the tablet. Allowing for different viewing angles depending on your preferences. On the right is the spot for the tablet. It's a sleeve that fits snugly to prevent the tablet from moving and has a velcro closure.
The sleeve has cut-outs for all the ports, speakers and cameras. The sleeve actually rotates to allow viewing in either landscape or portrait modes. On top of that the sleeve is secured to the case via a snap button. Which can be removed for a more comfortable experience. Because the case can fold backwards but the spine is stiff and it makes holding it awkward but its much nicer to just unbutton the sleeve.
