In the market for a simple iPad case? Check out the Booq Boa Folio. It's similar in design to the Apple iPad Case, but made from, you know, quality components.
The Booq Boa Folio for iPad comes in an assortment of colors and constructions. At $50 for the base model, it's not a significant up-sell from Apple's own case, but its ballistic nylon shell does make it a significant upgrade.
If you're feeling more executive, the $90 version of the Booq Folio for iPad comes in gray twylon with genuine Nappa leather accents. It costs a bit more, but it's hard to argue that it doesn't look smart.
Since buying an iPad, I've personally had two Apple iPad Cases completely and totally, fall apart on me. If you have suffered similar misadventures while in possession of Apple iPad Case, please sound off in comments.
