I think the hype is partly because many people (myself included) really like, even love React (and Flux). So being able to use it for native apps is great news for us.
Exactly this. I don't care about cross platform development. But I'd love to be able to develop UI's on Android using a similar paradigm I can do on the web with React. The main downside for me is that it's JS, not Java.
My day-to-day is very heavily skewed to app development rather than web development, but in my off-time I've been messing with React/flux. I have no issues with writing the objective-c, but the unidirectional style of React has been a real joy to work with and I've been thinking "How can I best imitate that while working natively?"
This could be the answer to that, and I wouldn't need to hack my own idioms together.
