I got the Samsung Galaxy Tab S2 Nook when it was released and today took it to the Apple store to compare it to the iPad Mini 4. The store was so crowded that I was able to spend about thirty minutes there without ever being approached by a salesperson. Many people online say that Apple's tablets are the best so I felt like I should look at both options while within the return window of the Nook purchase. Both tablets are very similar but in terms of screen and feel I prefer the Samsung. Most people seem to love the metal back on the iPad but I tend to prefer softer touch materials. Both tablets seem solid and well built. Both appear fast and fluid and either tablet will obviously get the job done. The iPad Mini 4 is supposed to have 10 hours of battery life and I am getting about 8 on the Samsung, so that is definitely a score for the iPad. In terms of apps, I haven't looked for an app on Android and not found it and I would probably need to look at the app website to notice if it was "tablet optimized." Maybe an app designed specifically for a tablet makes more difference on a screen larger than eight inches but I just haven't noticed problems with scale.
The Samsung S2 has been criticized by some reviewers as too expensive but the Samsung Nook very comparable to the iPad Mini 4 and is clearly a better bargain. The iPad Mini 4 16GB is $399 and to bring it up to 128GB is $599. The Samsung Nook 32GB is $359 for B&N members and with a $59 microSD card brings it up to 160GB for $418. Two years of accident protection on the on the iPad is $99 and is $79 on the Samsung Nook. Plus the Samsung Nook has some specific features that I appreciate but other people might not, such as Microsoft Office, screen synch to my Samsung phone and television, and the ability to read e-books free for an hour a day in B&N stores. I also just prefer the Android OS, which I already knew from owning an iPhone 6 Plus. So visiting the Apple store made me realize that for my needs the Samsung Nook was the right decision. I would only get an iPad if I owned other Apple products.
