There was a time when Barnes & Noble was so big, so dominating, that even Tom Hanks managed to look like a jerk when he played a book-chain executive. But times have changed, and as people began to order their books online -- or even download them -- B&N found itself struggling to keep up. After losing a lot of money last year, the company decided it was time for a change: It vowed to stop making its own tablets, and instead team up with some third-party company to better take on Amazon and its Kindle Fire line. Turns out, that third party was none other than Samsung, and the fruits of their partnership, the $179 Galaxy Tab 4 Nook, is basically a repackaged version of the existing Galaxy Tab 4 7.0. Well, almost, anyway. The 7-inch slate comes pre-loaded with $200 worth of free content, and the core Nook app has been redesigned to the point that it actually offers a better reading experience than the regular Nook Android app. But is that a good enough reason to buy this instead of a Kindle Fire? Or any other Android tablet, for that matter?
