I can't decide if I should buy a smart cover and a back piece from eBay or if I should wait for a case that has both functionalites. I liked the pixelskin hd wrap design but I want the magnets in the cover and others cases like STM skinny and incase magaine jacket are close calls but leave parts of back exposed or don't have magnets in them. Trying not to spend slot. Should I go for smart cover or wait for new cases? Anyone heard of news stuff coming out?
