This is the case I DIYed recently.

It's working pretty well.
The case is providing some angling for reading which is great. It also has the front which keeps away dust. But there's just one big drawback. When putting the ipad into the case, the awesome design and the "slimness" of it cannot be seen.
So I went and bought a silicone case for home use (the book like case was meant for on the road use anyways). Now this comes with all the disadvantages the case I made doesn't have (or whatever other book like case one uses).
So I decided to make a wooden slip-case where I can fit my ipad including the silicone skin. I'm really exited on how it'll work out.
