I bought an iPad 2 32GB WiFi + 3G (AT&T) model at Walmart this past Friday. After unboxing and using for a little bit of time, I noticed the entire bottom portion of the device does not look like it is "seated" properly. I can actually push down on the screen area and it sinks in. It sticks out from the bottom of the device noticeably when you hold it on the angle to see it. Should I return it to Walmart or take it to Apple for an exchange? I would say that it's a manufacturing defect but it's hard to say. I don't think it could be easily fixed. I'm not sure if Apple would take the exchange. I don't know if I want to risk another Walmart defect of the same sort on their shelf.
