This +100. I'd pay a reasonable amount for my Google Voice numbers, too, if it would ensure that I don't lose them on short notice.
I am OK with paying $6/user/month for the new plans but they don't include Google Voice, which is $10/user/month. I would be ecstatic if they had a cheaper plan that included Google Voice or if they allowed me to migrate my Google Voice number/account to a regular Google account.
