Of course people who buy books from Amazon are precisely the type more likely than average to embrace EBR. I wonder what the numbers are overall.
I think this must be good news for the book industry. I don't know the numbers to back it up, but I think people with EBR buy more books than they otherwise would, if for no other reason than to justify their purchase of the EBR

. Seriously, the convenience factor and instant gratification spur a lot of buying, I imagine.
