One of Incipio's first iPad Air cases is a mostly new product — not just a rehash, it's actually two cases in one. Watson Wallet Folio ($50) combines a faux leather folio with its plastic Feather shell. The latter can snap in and out of the former as needed, which is a pretty cool feature. Inside the folio, there are three credit card slots, and it can also be used in a standing position. Watson Wallet Folio comes in five colors.
