I'm now part of a team working on a new product that just launched (not Google). Every morning I go in and look at the dashboard, which shows the email addresses of the last 10 new signups. About 6-7 is gmail, 1 yahoo, 1 hotmail. There's usually 1 that's a custom email like from an unknown domain. I don't have hard stats as I don't have access to the user db, but I've been playing this game for 1+ month every morning, and it's the same pattern all the time. This is for early adopters. Also, from personal experience, most of my acquaintances, whether technical or not, are migrating from yahoo/hotmail to gmail. It's pretty common for me to have to remove somebody's old yahoo email address from my contacts because they finally got a gmail address.
