Agreed - the only one I have actually used is GAE, and I was definitely not trying to endorse the other services as "too good to beat." Just trying to say that with all the different stacks out there for different languages and purposes there will be a benefit to specialization, which might not benefit from amazon's skillset as much as the provisioning of VPS's and other infrastructure has. For python hosting, GAE is probably the only real competition at this point. There is a HUGE opportunity to eliminate sysadmin work on all these stacks for smaller developers especially. I am just not sure if Amazon will domiate both the infrastructure and platform layer.
