Native apps or die. I won't use anything based on Atom or Electron.
The reason is that these "cross-platform" applications on top of web browsers are basically complete operating systems emulated on top of the underlying OS. It's worse than turtles all the way down; they're sea urchins: fragile, prickly, and lethargic. And these memory-hogging leviathans multiply faster than rabbits so developers don't have to get their "hands dirty with details" like fast, efficient, proper software.
Just because someone can write a ray-tracer in BrainFuck doesn't mean NVIDIA/AMD/Intel should steer the whole industry to using something impractical because developers get excited about all of the "possibilities."
