The context of the snippet you quoted is "Spend money on tools that make you more productive." In other words, don't skimp on a tool or service that can simplify an operations task, if the result is that you can focus more time on features. I don't see the implication that operations is unimportant. Having a laptop/PC that you can develop on is important to developing a product, but no one would suggest that the author design one from scratch. Everyone (excepting perhaps Richard Stallman) would say it's better to just outsource that task to Apple or Lenovo.
