I don't actually think it is easier to get adoption. The major mobile platforms have SQLite built-in (under the hood in the case of Core Data). I think that's actually a strong barrier to overcome.

Furthermore, mobile is becoming in-demand or even core in both consumer and enterprise. For enterprise especially, though, you have to think of it as mobile + sync, not on-device only.

Turns out sync is the really hard part when you want to build something that's robust in the face of poor network connectivity.
