Then you have to factor in all of the people that were already using Hotmail.
I haven't used my hotmail email since gmail came out. But it is still active as I use it to 'try out' all these MS services when they come out. The day Outlook.com was released, I quickly logged in, checked it out, shared the news with some friends, logged out. Haven't logged back in since then (and don't plan to)
It's more like "a G+ account is associated with the google services account you use." You still log in to the service as you did before, but G+ just sitting up there in the corner, waiting.
What? I haven't heard of that and I have a gmail account (no G+).
