My #1 favorite feature of this Tuff-Luv case for iPad is the multiple viewing angles while in landscape mode. It cleverly folds its front panel back whose five snaps can secure a second flap from the back panel that holds up the iPad. Different angles make sense for different uses and contexts. A flatter angle makes sense for writing email and notes or surfing the web, but a more upright angle makes sense for viewing movies and the like. I've used this case with my iPad on the sofa, on the plane, in a lecture hall, on my desk, and it works really really well, and with style to boot. So far its structural integrity remains intact.
Second to that is the feel of a leather case on one's fingers. The iPad experience is about touching, and this leather cases enhances the effect. This is something only a great poet can describe well, so you'll have to try it for yourself.
It works for portrait mode to quickly open and access the iPad, then quickly reprotect it. Or if you're using it like a tablet, holding it with one hand while operating it with the other. I can't be sure how to improve it there (maybe a strap?), and it's at least as good as any other case I've touched.
And Tuff-Luv went the extra mile, rerouting shipments from China due to that Iceland volcano. I wasn't in a rush, but I appreciate their expediency.
