Hi guys I have a iPad 4 as my iPad 2 went faulty. But after a couple of hours with my iPad 4 I notice the bottom left is hot, the other areas are fine it's just the bottom left. This never happened with my iPad 2. I'm not bothered but just want to know its a common thing for that area to get warm otherwise I will return this for. Replacement. If you put your iPad in a carry case cover type thing you likely won't notice, it has to be a naked iPad to notice probably. Any advice would be great.
