I'm not sold two-way binding tools get inherently complicated, I just haven't seen this increase in complexity in our current app which is quite large. But I am attracted to react for the reasons you mention, the virtual DOM aspect is very nice so I'll give this a shot.

Although even though ReactLink works it a.) feels like quite the hack (i.e. not very composable) and b.) is a more code to maintain still when it comes down to it.
