Like many others here, I ended up buying the Poetic Slimline case on amazon for around $5 and there seems to be no end to these types of cases that are available. But here's the first one I've seen that actually emphases it's "extremely light, slim and functional" aspect. http://www.cultofmac.com/253710/ultra-light-lioncases-now-available-for-the-ipad-air/ There's no mention of weight on their website so if anyone takes the plunge and buys one or is able to find some sort of comparison to the Poetic, I'd be curious to find out what it is. This could be a real contender for me. It's all about the weight!
