Oh for sure. Huge assumption on my part. I just feel like 90% of people I work and interact with have a gmail account, and the last 5 companies I've worked at used gmail. I think the last time I setup Apple Mail was for my Grandma so she could see her old Cox account emails and Gmail emails in the same app.

The default Mail app still doesn’t support push Gmail, does it? That’s the only thing keeping me from using it. I otherwise strongly prefer Mail.app.
