Is the heat and issue? I have a 4G - wifi iPad and during angry birds and using safari it gets noticeably warm. I don't care what my local news says, but from the tech community is this an issue? Can the heat damage my iPad? Just some note I am mostly on wifi My brightness is always 100% ( don't know why I just like it bright!) Only use smart cover Also I'm thinking about getting a speck or belkin snap case, will this cause it to stay warm or heat up faster?
