A $600 laptop bought new should absolutely still be useful in 5 years. It should be useful longer than 5 years. That people’s standards are so low is a condemnation of the modern computer market.

I would, and have. I disagree that I shouldn't expect a new laptop to still be useful (not perfect, not great, just useful) after only five years.

If it's not even useful after such a short time, then I question whether it was really fit for the intended purpose even when it was new.
