I stumbled upon this forum while searching for more reviews on this case. I had the Incase cover for my old MacBook Pro, and because it worked so neatly, I got their Hardshell Case for my newer MBP.
Incase stuff is usually very promising, and that was why I turned to their convertible book jacket first when I was looking for a case.
I live in Hong Kong and got my iPad the day it came out (I was in the Vegas earlier, but wanted to avoid tax - Apple products in Hong Kong are the cheapest, even online). Now, the case is available on the HK Apple Online Store as well.
I'm ready to get it, but I'm afraid of the iPad slipping out issue. So I sent an e-mail asking Incase whether or not they still ship the previous version with the sliding out problem. Hopefully, they're replacing all the Incase convertible book jackets online, but we'll see when they reply.
