I just bought a Coveroo cover for my iPad a few days ago. I like several things about it. It makes a nice cover for the front, and fits on the back when in use. I can even carry a couple of microfiber wipes between the glass and cover. I am still looking for the perfect case, and for a good charger/speaker system.
I got to thinking about the small gap between the glass and Coveroo. I have to wonder if some type of compact charger base could be combined with a folding cover over the glass. When opened, the cover forms a thin speaker system that runs off the charger base. The speakers would have to be several times louder and better than the iPad built-in speakers.
