Does anyone use a case and sleeve for their iPad Mini? My backpack doesn't have a separate compartment or a laptop sleeve installed, so I'd like to get a sleeve as well, but from what I've read on so far, it seems like a lot of people don't do this. My main concern is that the sleeve won't fit with the case on. If anyone is/has done this, I'd really appreciate it if you could list what you use/used.
