@cliff-g: I'm sorry to hear of your disappointment. The Galaxy Tab S2 launched in 2015 on Android 5.0.1, and can be updated to Android 7, but there are no plans for further Android versions to made available for this model. I understand that this isn't ideal, however typically our phones and tablets will receive software updates for around 2 years from the release date.
Agreed, what gooid is it if it is 2-3 years old, still has good battery life and still would work fine if the OS could be updated for 4-5 years? Basically samsung is saying that you need to spend $1000+ on their device every 2 -3 years if you want it to work with today's apps. Remember to choose the more costly approach. You should buy a newly released device, not last years model, when it first comes out because the clock is already ticking on the OS. I do like my tab but really? Only two years? How about charging me $50 a year for the next 5 years to keep it current? I'd pay that.
