I like this folio cover. It doesn't add too much bulk to an iPad Mini, it doubles very well as a multi-angle stand, and it auto wakes/sleeps the iPad's display whenever the front cover is opened or closed. The "anthracite" colour of the cover is darker than some of the promotional photos would have you believe; it's a very dark grey that almost borders on black.
The fabric of the cover won't be to everyone's taste and it may stain, but I quite like it, and the fabric's colour is so dark that only very severe stains would probably show up anyway. Though a tad overpriced at the moment, Case Logic's SnapView is a desirable, no-nonsense option for any iPad Mini owner.
