I installed a new app the other day, I forget which and holding down back pops up a question on whether to exit. Other apps only do that when hitting back from the main screen, or just close automatically.
But not a lot of people know of the distinction of hitting back vs. hitting home. I think the Iphone's 1 button helps with that, but given choices, people don't always understand them all.
