That's the rub. Google products work great, and I actually prefer their calendar and mail program to Apple's, but dumped them because Google also scans all of our stuff and connects us where we don't want to be connected in order to gather information to sell. Google going through all of my contacts and connecting email addresses, phone numbers, birthdays, etc., with people was really angering me. I'd already stopped entering birthdays and other personal information, which was too bad because contacts are great for organizing all that information. I even stopped using my family members' real names, but Google still managed to make connections between people and their various email addresses and online accounts.
The final straw was seeing links from Google in my contacts to friend's other online accounts, and after clicking on two of them I could see what they'd watched on YouTube. I could see that info despite their never giving me permission to do so. That meant that anyone with my email address and private information in their contacts list could see my other accounts too. No matter what I did to protect my privacy, those efforts don't make a difference if my info is in one other person's contacts list. And, because Google scans our contacts, emails, and documents, anyone emailing with us who does not even use Gmail loses their privacy too.
Too creepy for my taste so I dumped all Google, after managing my life and family's lives in Gmail and Google calendar since their introductions to the public. It's really a shame because I do think their programs work more reliably than Apple's and are as if not more intuitive. At least, though, at the moment, Apple makes its money by selling me its overpriced stuff, not from my private information and shopping/searching/entertainment habits.
