I completely agree with your analysis, but want to add one point. One of the reasons why IaaS is easier to adopt than PaaS is that the vendor lock-in is lower. Porting a virtual machine between providers is not an easy problem, but is well understood. PaaS lock-in is much greater, as most PaaS providers force your application to use their APIs.
This is one of the huge benefits of OpenShift. It's the first PaaS I feel comfortable using. But it is not as mature as the other offerings so I am nervous about using it for critical applications.
