Hey all, I took advantage of BestBuy's sale on the iPad Air smart covers, and mine is shipping this week. Can someone point me in the direction of a good hard case for the rear of the iPad? I am looking for something that will work in conjunction with the Smart Cover and preferably lock the Smart Cover against the iPad. If the case had a magnet on the rear (to keep the case tight against the back when opened), it would be perfect. Thanks in advance.
