Could not disagree more with the article. In my experience, well designed SPAs are almost always better and lighter than multi page apps. The fact that a lot of SPAs are implemented quite poorly is a different story. In actual fact, whether a web app is single or multi page is merely an implementation detail; in both cases we're just passing information back and forth between client and server. With multi page apps, you transmit and parse full markup each time. With SPAs, you do it once and then mutate as needed. In that sense it's more efficient and I can't see why that's a bad thing.
