Of the numerous differences between the Samsung Galaxy Tab 4 NOOK 7.0 and the Kindle HDX, one of the more notable is the memory capacity. Another significant difference is that the NOOK has both front- and rear-facing cameras, while the Kindle HDX only has a front-facing camera.
The NOOK has 8GB of built-in memory, expandable to 32GB with the use of a microSD card, while the Kindle HDX offers various models with 8, 16, 32 or 64GBs of built-in memory but has no option to expand. With a 2.2 GHz quad-core processor, the Kindle HDX boasts more processing power than the NOOK, which uses a 1.2GHz quad core processor. Both devices are Android-based, however, the NOOK 7.0 allows users to access the Google Play store, while Kindle HDX users only have access to the Amazon App Store.
Foxconn, a China-based company, manufactures the Kindle. Samsung manufactures Nook, but the company hasn't entirely managed to translate its track record with screen resolution on Galaxy phones to its e-book reader. Nook's resolution approaches 1024 by 758 pixels, whereas Kindle's is 1430 by 1080 pixels. The Nook is also roughly $100 cheaper than the latest Kindle.
While both devices offer an array of features, one of the more noticeable differences is that the NOOK offers seamless integration with YouTube, Google Chrome and Gmail. The battery life of the NOOK is up to 10 hours between charges, assuming general use and video playing, while the Kindle HDX lasts up to 11 hours based on mixed general usage. The weight difference in negligible, with the Kindle HDX weighing in at 10.07 oz, and the NOOK 7.0 tipping the scales at 9.74 oz.
