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.
