As others have said, I have never experienced "physical button death" on any phone, tablet, Kindle, old MP3 player, shaver, PC keyboard, TV remote control, Bluetooth mini keyboards, mice, controllers, etc. They are typically rated for tens of millions of activations (that will far exceed the life of a typical non-removeable battery). So unless you're doing something seriously wrong, it sounds more like a personal excuse to buy another Flagship phone than any factual survey.You do know that physical buttons will fail with use, just normal use. Every-day like pressing of the buttons will eventually kill the buttons depending upon how well they're built.
Same goes with "but who could possibly want more than 64GB store" A: A lot of people for a lot of reasons. In fact 128GB Micro-SD cards are now the most popular size. Again, this sounds like you're simply looking up the maximum typical internal memory size of typical "form over function" Flagship phones that are 'too posh' to give users any kind of flexibility, then dictating arbitrary limits around that and demanding users lower their expectations to match the lowest common denominator to try and sell "less is more" on the back of another price hike. That 'elitist snobbery' based marketing stuff worked a couple of years back, but as the article topic states, people are starting to see through that stuff these days as being little different to the gushings of audiophile magazines.
