When I got my ipad 3 I bought a Smart Cover. A few months later the ipad was knocked off a table and a corner got dented. A few weeks after that the home button started giving problems but the warranty was voided because of the dent. I'm still using that ipad3 but have since bought a sturdier but heavy cover. It seems like such a waste of the ipad air to get a heavy cover, but it seems almost a necessity.
