You have a point, but App Engine has the following issues: - lock-in (migrating your apps to another platform will be extremely hard) - Less control over your backend

IMO these two issues are enough to keep most of the app developers away from App Engine.

This is foolishness. Your biggest risk is that your product will fail in the marketplace, not that for mysterious-and-unnamed-reasons you will suddenly have to migrate off the platform. As far as "control" goes - there is nothing about appengine that prevents you from running specialized application code in other parts of the cloud. But it's a pretty exotic need.

I know a thing or two about App Engine too, and I disagree with you.
