Personally I think smartphones will never be good at known-goal interaction. They're general-purpose devices with a hilariously low-throughput interface that need to accommodate low-tech users. You're always going to have to navigate a bunch of screens to get to any given function because the real estate is so small.
Could apps be better? Sure. Can any app get as good as a button that's already right there when you realize you need a replacement? I don't see how.

Anytime I pull my phone out to do something specific I end up checking twitter and forget what I wanted to do.
Edit: and the answer is pretty clear, I think. If people actually go for this, it'll be a massive advantage for Amazon. It essentially banishes competition permanently for people who use the button regularly. It'll also make people much less price sensitive. So I completely understand why Amazon would try to push this. I just don't understand why anyone else finds it interesting besides that.
