Google is charging per datastore operation, and last I saw was defining each entity returned as an operation.
If you were building a social network or twitter clone using the techniques they recommend in this talk at GoogleIO: http://www.google.com/events/io/2009/sessions/BuildingScalab...
...you could easily pull back a hundred entities each time you pull someone's feed. Each entry is a separate entity. It'd cost you a buck for every pageview.
Is that an accurate assessment?
