You don't need a reactive front end framework, but not using two way data binding at this point I think is crazy. Binding is an EXTREMELY powerful tool.

I have yet to see something that handles updates from other sources well. Meaning that the page the user is on is updated by some other person or process and those changes are propagated correctly. I still have events that fire when something is saved that check to see if it was modified while the user was in it.
