Traded in my 1st generation iPad at Target for an iPad Air. The 1st generation had an Otterbox Defender case on it because it was occassionally handled by a 6, 8, an 10 year old and I didn't want to see it dropped, wet, etc. It looks like Otterbox has yet to release their defender case. Are there any other good suggestions? Anything that will mildly or adequately protect until they release theirs? Thanks.
