I picked up an iPad Mini Retina yesterday for my wife as well as a regular iPad Mini case. It's one of those folio-style cases with the plastic shell that holds the Mini. Well, it turns out the rMini was just a bit too big to fit in this style of case. It even cracked one of the corners from less than a day of use... Has anyone else had issues getting their Mini to fit into certain cases? Which cases that you've used do actually fit?
