I'm buying a tablet soon with my Best Buy gift card. My limit is around $200 (+ tax). I've narrowed down my choices to: - Samsung Galaxy Tab 2 7.0 (8 GB) [Best Buy only sells the 8 GB version] - Kindle Fire HD (16 GB) - Nook HD (16 GB) If I buy the Galaxy Tab, is 8 GB enough to hold a bunch of apps? I will be storing my music on a microSD card. What are the benefits of the Kindle Fire HD and Nook HD? Do they have a varied app selection? I know the Amazon Appstore has most of the same apps as Google Play (aside from the Google apps, of course).
