I have the Apple Smartcase. I like it but I'm not happy about the fact the the cover doesn't seem to be held magnetically on the back of the iPad when I flip it to use it.
I'm going to go back to Apple and see if this is a quality control or design issue.
My old iPad2 cover stuck to the back great. This one does not.
That's a design issue as you call it or a design choice as Apple would call it.
