I expect to get the rest of this decade out of my Steam Deck so IDK, very different to my normal expectations for a computer. The Steam Deck also defines a floor that will allow compatible games to be very performant on the Steam Machine so I think that will help the Steam Machine have a decent lifespan.

I also think on some level we need to start resigning ourselves to getting 10+ years out of our computers!
