Workspaces mainly focuses on enterprise customers whose administrators (with good reason) do not like to be surprised when new services are added to their users' accounts without some kind of vetting process by corporate security, legal, etc. I know many "powerusers" like to sign up because it lets them use "gmail" but with their own domain, but I suspect this is a niche use case compared to those who use it in corporate/enterprise environments.
