That ship has sailed. A far as most are concerned gmail is email. So that is now the reality. Google has successfully, without any resistance, assimilated email and the web.
I run my own mail and I faithfully avoid chrome as much as I can but the ship is long gone over the horizon.
Sad. But so it goes.
Not true for me. All businesses of any size, and even most small businesses, that email me have their own domain. Individuals use a variety of services, and even one or two non-geeks use their own domains.
