[Snip SPAs reasons that aren't inherent to SPA] > Most of the mobile devices you're talking aren't that powerful, so loading them down with a bunch of JS to run, makes for a really bad for UX. Even mobile CPUs are more powerful than your average cloud vCPU. They get refreshed much more frequently if for no other reason than the batteries give out. That doesn't even take into consideration the fact that the server is rendering x requests vs the client's one. Any spend on server hardware to make it fast will never make up for the network latency vs a well built SPA that can avoid refetching some data again entirely. Page one, server render is faster. Every subsequent navigation will favor a well built SPA.
