Nice article. Taking the Amazon site as an example, I think it highlights exactly why a sites accessibility is hard to judge. It comes out well in the Wave score but for me trying to navigate it via a keyboard is almost impossible (Windows: Chrome, IE11 (Firefox fares slightly better). So there are so many aspects to it and clearly browsers have their own impact on it as well.
