I'm still thinking about upgrading and still mildly annoyed about the Apple case/cover for the Mini 4. Does anyone have personal experience with any of the most popular SmartCase-style case/cover combinations that are available for the Mini 4? Khomo, Moko and JETech all seem to get very positive reviews on Amazon, all claim to have a Mini 4-specific case/cover...and all three look very similar, other than color. Comments on fit? Comments on how well the magnet works to turn off the iPad? Comments on how firmly the magnet holds the cover when you're using it as a stand? Any other comments? Thank you!
