I'm building business application at my job. Users navigate (filter, configure, visualize 3D models) huge lists of data (bill of material, product structures). SPAs are heaven sent. Delegating every filter or configuration action to the server would be insane. Same with server side paging. Another example is 3D viewing: When selecting a part in the viewer detailed data should be displayed. A round trip to the server for this? No, thank you.

I have to heavily disagree with this post. Which by the way lacks any in depth arguments.
