My three runs hotter when I am downloading tons. Remember the battery has 70% more capacity, GPU went from a single core to a quad core, and the chip is teh A5 dual core. What do you really expect? The only time that mine, or customers have really heated up was when we were first setting it up, and sync'd all of the apps to download via the cloud. Other than that, I can't say that I have noticed an increase in temp at any other time.

And the screen is phenominal!!
