I think the key point here is "outside of work".

I think the thrust of this article is mostly work related. He talks about being a consultant and seeing people waste so much time on SaaS tools, for example.

Personally I don't mind using "throwaway" services in my personal life - all your examples are things that don't matter - but for important stuff like work I want one place with all my information - not lots of crappy silos that don't integrate that I have to search for that key bit of information.
