Title says it all. I'm looking for the thinnest, most straightforward, "minimalist" case (or cover) +keyboard available for my iPad Air which currently has a Smart Cover on it. I realize there are probably a few options since Moshi and the rest announced theirs, but I thought I'd solicit the opinions of MR users first since I suspect there are a few like-minded people here. Looking for something that is understated and as slim as can be, as well integrated as a third-party case/keyboard can be, and with solid battery life. Willing to pay a little bit of a premium. Suggestions appreciated!
