Its not all bad for BN.
Digital content sales — e-books, digital newsstand and apps — were up 65 percent for the quarter and 119 percent for the year, “growing comparable digital content sales to $483 million for the full year.” Digital content sales weren’t broken out for the quarter.”
However, agency pricing might account for that. Post-DOJ settlement, BN may be less competitive in digital sales vs. Amazon.
It looks like BN reading devices may be going the way of the dodo bird. Maybe Microsoft will take over future development of the Nook Tablet. Don't see them investing in e-ink devices though.
