To be fair...Apple advertises the iPad being used outside, in the sun, at the beach...and reading a book. You don't read a book for 5 mins.
It doesn't have to be scorching outside to heat up metal/plastic...a cool 75F degree day is still gonna get materials above 90 degrees...and a more normal/average 84F degree day (us NorthEast people) is going to get any device hot.
Again, all this said, Apple is the one who is promoting outdoor use of the iPad and for extended periods of time (reading a book). Don't blame the consumer for buying it and having it overheat and/or break while it's being used as-advertised. And on a side note, my multiple iPods and iPhone have been out in scorching 95F+ degree weather (in direct sunlight) for entire vacations and never had a problem...nor did my old Sony Discman.

Doesn't matter what Apple says, if Apple says your going to live forever so jump off a cliff. Are you going to do it?!?! NO. Quit being stupid lemmings, its obvious that you can't use it too well in bright lights like sunlight. I knew this pretty much the day I sold my kindle to get my Ipad and expected it not to work too well outdoors.
