Hamid et.al.,
   Since I'm using the iPad at American, I can tell you how we use them and 
the environment they operate in.  I would echo Hamid's observation that it's 
a completely different application and environment than in a Lancair.
   First, since we don't use them for navigation or attitude (and why would 
we with the cockpit instrumentation we have?), the iPads are normally only 
used for reference to an airport diagram or departure procedure on the 
ground and in the initial phases of flight.  Once we get past the STAR, we 
normally turn them off until we're getting set up for a SID and instrument 
approach prior to arrival as well as displaying the arrival airport diagram 
during taxi in.  Sometimes we'll turn the units on in flight to reference 
something in a manual, but for most of a normal flight, the screen is turned 
off.
   Also, as Hamid mentioned, we operate our iPads in an air conditioned, 
pressurized environment.  They aren't under a plexiglas canopy where they'd 
subject to continuous sun exposure.  I'm not aware of anyone to date who has 
reported one overheating.  I'm guessing that would have been a major road 
block to FAA approval of their use in airliners.
   So far as I know AA bought standard, un-modified 3G models of the third 
generation iPad.  They use stock software with all of our Jepps displayed on 
a proprietary app from Jeppesen.  In the 737 I fly, the iPads are mounted 
using either a RAM suction cup mount to our side windows or a tray type 
mound that attaches to the side window clipboard.  Because they're facing 
into the cockpit with the backs of the units shielded from the sun by the 
mounts, they get no direct sun exposure at all.
   Hope this clarifies some of the questions,
   Skip Slater
