I'm debating about whether to get the Smart Cover with my new mini. Right now, I'm leaning towards holding off because I'm thinking that I might would rather just have a slip case of some type. In fact, I already have an old one that might work fine with it. With my original iPad 1, I have the case that was being sold with Apple at the time and it has served fine. But one of the advantages of the mini is it's light weight and size for reading, which will be my primary use. Any opinions?
