You named a few Google products to be contrarian and think that Google is far from indispensable? I'm calling bullshit because I'm willing to bet most of the non-Google products you use use Google somewhere in the chain.
I wasn't attempting to be contrarian, I was saying alternatives exist. Even in a business context. Our company uses Google for many things, but there are alternatives. The switching cost is high, but that doesn't make Google indispensable in my book.
