I turn everything on and sign in everywhere. It's super useful to remember both what I searched for and where I've been. I use Google stuff because of the tracking/personalization, like Calendar is integrated with Gmail, or Maps can show my contacts, or Search knows where I am, and YouTube makes OK (not great) recommendations based on my history. I'd gladly pay them to handle all this for me (instead of ads), especially for search and maps.
