What's Amazon in this example? Hacker News? Google Search? All of these are problems that are still perfectly well suited to server-side HTML generation - the dominant user interaction replaces all / a significant part of the page, with relatively minimal non-database state preserved between interactions (a cart for amazon, your user name, your search term). All of that can be built perfectly simply by a traditional request-response cycle with some Javascript enhancement. Going SPA for most "webapps" (if app is defined as something that isn't purely static) is a massive waste of time. Use Javascript on the few items that require more interactively, but if most of the time major interactions are replacing > 50% of the UI, a SPA isn't buying you anything.
