1 Google apps (paid), there is a phone number to call. I spent several hours on the phone with a very knowledgeable person helping me troubleshoot a sync issue.

2 Hardware, my android watch died. I called the Google play support number, again talked to a very knowledgeable person who gave me a couple of troubleshooting steps, and then promptly replaced the watch.

3 Google adwords. We regularly talk to people at Google adwords, regarding billing and support issues. I also work with people who speak with support people for Google places (or my business or whatever they're calling it today)

In my experience, Google tech support is great when it's for a product you're paying for. That would be my concern getting 60 days free here... If I was using this for business (and not just messing around) I'd rather just pay for it and know I can get support.
