The key thing to remember is that this is a preview release, available only to a small number of users. Google is probably keeping an eye on ways people are trying to break out of the sandbox and fixing bugs with their SDK and infrastructure.
Google is trying to get people to write applications in a way that CAN scale, not necessarily something that is scalable at the moment (see the resource limits). Once the pressing issues are ironed out I am expecting to see more reasonable terms (in the free to pretty cheap range).
