Having themed names for successive releases is childish and prevents the software from being taken seriously in the business world.
That's like expecting people to spend real money on something called "Chicago" or "Cairo"; or "Willammette", "Nocona", "Tumwater", "Lindenhurst" or "Dobson"; or "Banias", "LaGrande", "Tanglewood", "Tulsa" or "Vanderpool".
Oh wait, they do that.
