Simply, Apple should have better future-proofed it. Especially as it doesn't need to rely on a battery, Apple should've went all-in by using a A9X perhaps even higher-clocked than in the iPad Pro instead of the A8. There's no debating how much more power that could have provided which could make for some truly amazing apps. Especially as game developers get on board, having no performance bottlenecks could really make the Apple TV a very worthwhile box for $149. As it stands now, I'm not entirely convinced that it offers enough to differentiate itself performance-wise.
