Barnes & Noble and Samsung on Wednesday unveiled a new co-branded tablet called the Samsung Galaxy Tab 4 Nook that will replace B&N's own Nook tablets.

The 7-inch tablet will sell for $179 after a $20 instant rebate, the same entry price of the non-branded Samsung Galaxy Tab 4.

The move had been expected, since Barnes & Noble said in June it would team up with Samsung to develop Nook tablets that would be available in August.

For the first time, the Nook will have a front- and rear-facing camera. It comes with more than $200 in content from the Nook Store, including books, TV shows and magazines. However, apps are limited to Nook apps rather than the full suite of Android apps available on Google Play.
