SimpleDB now lets you: SELECT foo FROM bar ORDER BY foo.field DESC LIMIT 1

This is important, because that is a very common query to get the latest/last item from the DB and you could not do it before.

My next project will be using SimpleDB. I've played with it, and SQS, and the inability to do that last query was the holdup.

SimpleDB is now a viable choice for many applications.

Follow-up: SimpleDB's perl library does not function as of this release.
