I still have a Google account (in fact several) but I hardly ever log in. I use it when I have to for work, but if I have any choice I use Microsoft Office instead of Google docs. Mainly I use JIRA, Slack, and tools from other vendors.
I use Fastmail and EM Client for my personal mail. You get what you (do or don't) pay for.
I have a Fitbit Alta HR, mainly because it is smaller than a conventional watch. I am not going to get rid of it, but I am certainly not going to replace it with a Google product. I probably won't be able to anyway since Google will probably kill it in a fit of mindlessness soon.
