Yes. Of course. Because there's no inherently consumable parts. There's no reason that this shouldn't work 10 years from now (like original Chromecasts do, or first-gen Roku devices, or even 1080p TVs). Why bother buying into something with a limited lifespan?

Why shouldn't we? It's a consumer device that happens to have a perfectly good general purpose computer inside it. There's no reason why it shouldn't continue to work until the hardware itself fails.

And so does the environment when you throw it in the trash after 7 months.

It’s not about the price in USD, it’s about the price in CO2 production and human suffering from mining and manufacturing.
