As a former iOS Developer for American I can say that while there is a rather large effect on the entire network, it pales in comparison to the savings gleaned from having the iPads.

I couldn't give specific numbers on the lost revenue here. It could be anywhere from a few thousand to several hundred thousand dollars. But there are people at the airline who analyze the cost of delays and they can be pretty significant - more so if this occurred at fleet launch in the early morning (though that doesn't seem to be the case).
