Yeah, killing inbox moved me away from google for mail entirely, and after that the dominos started falling. The only google product I use regularly at this point is YouTube, which I pay for to avoid ads.
IMO, YouTube is their only killer product at this point. Runner up might be Maps, which I occasionally use for Street View, but I've been able to get away with MapQuest most of the time for directions. Otherwise, I've completely replaced everything in the Google ecosystem and have been very happy. Sure, Google's got all the algorithms, but that's not something I want in the first place.
