APPARENTLY MY VERY BRIEF IN-STORE REVIEW HIT ON A KEY POINT: Apple’s iPad throws off much more heat: tests. “Apple Inc’s new iPad throws off a lot more heat than the previous version, lending weight to complaints on Internet forums that the hot-selling tablet computer could get uncomfortably warm after heavy use, an influential consumer watchdog found after running tests.”

But if you want to trade in your old iPad and get a new one, Amazon will take it.
