I know, there are a million of these questions right now all over the internet....but, I need some advice before laying out a big chunk of money. Coming from a 5S and need to upgrade. Want the dual cameras, so the Plus models are my choices. On the surface, the changes from the 7 to the 8 aren't that big of a deal to me, however, because I keep my phones for ~4 years, I wonder if the jump from the A10 to the A11 might buy me more longevity in the phone? While that makes sense, my only conundrum is that $950 for the 8+ 256GB is ridiculous, and I could save almost $200 by buying the 7+. Sure, the 7+ is more than powerful enough for my needs today, but three years down the road, that may not be the case. Thoughts? Comments?
