Re: Fixed battery = ripoff
I said pretty much the same thing for years, then I picked up an original Moto G - not quite $50 but still cheap. Fixed battery, was a difficult decision but I figured at the price that it might not be so bad. Still using it to this day 2 and half years later, easily get a full days use, often enough I eek out a couple of days. The point being that battery technology has improved and over the lifetime of the phone, which for the majority of people will be no more than 3 years, the degradation in the battery life won't be an issue.
I would still opt for a version of the S7 with removable battery if such a thing existed but I've changed my opinion on the battery issue to the point where I can live with a non-removable battery. These days you'll find it nearly impossible to find tablets with a removable battery, all kindles have a fixed battery, even my laptops have fixed batteries and yet I don't hear a storm of complaints from people about these devices because the batteries last just fine. As with all things, there will be batteries that fail early - warranty replacement usually takes care of this and if you are replacing batteries regularly with a modern device then it's a sign that the battery design is flawed and not batteries in general.
