Those of you comparing how warm your iPads are getting, please keep in mind that the presence/use of things like LTE can have a huge, HUGE impact on that sort of thing. I'm not familiar with what kind of antenna/chipset the iPad is using, but most 4G phone owners will tell you that 4G use on their phone = a warm spot due to how new and inefficient LTE technology is.
yes and it is UNACCEPTABLE
