I find it's often not, largely because the amount of focus on web apps means the native frameworks often are less productive by comparison than what is available for the web.
i don't see why i'd ever spend time on any particular platform when i could avoid it. I don't like any of them, but i still want my software to work on them.
When you need to release your application across multiple platforms? Yes. Not much else even begins to compare on that front.
