So, my title says it all i think. I bought the 32gb wifi + cellular ipad air yesterday. It is fast, sleek and beautiful. Then i started comparing it to my wifes ipad 4. The air feels extremely delicate (i am now regretting my choice of smart cover over the smart case). the glss actually bends with a little pressure and has an extremely hollow feel when tapped. Secondly, Siri seems muffled. Side by side comparisons with the ipad4 reveal a glaring difference. And last, my power button is looooose. moves back and forth and left and right. overall, im still happy.. just wondering if all these issues are common... i hope they are!!!!
