From other devs I know they have said React functionality on mobile is quite poor. Drag and drop and scroll, doesn't work as well, because the virtual DOM isn't adapted work to well on mobile. So for that reason, I won't use React, and rather go Vanilla or use Backbone. After getting burned by Angular, I'm really weary to adopt another fancy framework.
Drag and drop/scroll should work on the real DOM not the virtual DOM, no? I use Drag and Drop in a web app (using Om, which is a clojurescript library built on top of React) and it works just fine across all platforms.
