A nicely presented set of information on Cloud without any marketing bluff.

Vendor lock-in is a problem in Cloud, true. But at the same time for the economies of scale to kick-in it has to come from vendors with each individual company trying to optimise their platforms and APIs.
"Open" can not come from sets of individuals who have few computers to play around (as it is with most of "Open Cloud Forums"). Also the three main players of the cloud industry, i.e Google (SaaS), Amazon (IaaS) and Microsoft (PaaS) are on three places in the cloud spectrum. And interoperating these three itself is a hard problem . So most of the companies or individuals has no other option than to follow them. For example, when Microsoft comes with all the Azure service integrated with Windows next version, it will become the de-facto for "most" people.

The other issue on Cloud as I see is the myth about clouds on its ability to run "any" application. First the application should be scalable to run on clouds. Its very hard to get an existing application as it is and run on clouds and boast about the scalability. But this is exactly what is/was happening with most of the companies trying to move to Clouds.
Second is that not every parallel programming model is suitable in Cloud. Yes, map-reduce style models consisting of individual standalone worker nodes might work well. But MPI style models requiring. better communication infrastructure will suffer heavily on most of the platforms. Some people consider HPC and Clouds as "twins separated at birth". So considering cloud as a silver bullet will be a disaster, IMHO.
