There are many people who have older hardware. For example I write this on a 2009 Macbook. My parents use older hardware still. And we're relatively well-off in a rich western country. These machines are perfectly fine to use for almost all tasks, but they're not powerful enough to run ten copies of Chrome. We might easily be able to afford that newer 500€ laptop, but for many people that multiple months of income. Not to mention the unnecessary waste the churn produces.
And also sometimes there is absolutely no need to buy new hardware! I find appalling that we need to upgrade our machines just because software gets more and more resource hungry. My parents as well use old hardware to browse, edit documents and write emails. Back at I home I still run a 10 year old PC with Linux and it just keeps running very well... No need to upgrade! I just think about the golden age of videogames and the software tricks developers came up with to make them run and the hardware those used to run on. Today basically you need to constantly upgrade your GPU if you want to play the latest cool game. Ridiculous.
