Yeah I don't know much about MongoDBs past transgressions as a company or have any experience using it so it wasn't intended as a criticism of the company. I just spent a lot of time learning exactly what all these DB terms mean and wanted to point out an inaccuracy so its clearer to people reading.

As you say, eventual consistency only comes in with multiple nodes. And unless you are willing to sacrifice availability, eventual consistency is the only game in town in a multi-node scenario.
