I knew a guy who was on his mission for the Latter Day Saints in the ghettos of Chicago. He said the number of people that called for a free Bible just because it was free was amazing... no interest in the LDS church or the bible, they just wanted one because they saw it was free on TV.
FleaBay has these for about 200-300 right now... although I'm not sure that's for an equivilent ibook (don't know, don't really care for Macs)
