prediction:

Lots of people will sign-up. These people will love the service. They will come to need this service for their businesses to survive and function properly. Two years afterward Google will do what they have done time and time again, close down the service - for unknown reasons - at every users expense.

Will it happen? I don't know but they just don't have my trust for the long term. Yes, I know that you can transfer domains fairly easily but nothing is ever that easy.
