For example, I only buy/use old high-end (for their day) business class laptops and put linux on them. They work for everything I need to write and surf.
I also bought an iPhone that was already a few years old and plan to keep it until it stops getting security updates from Apple. I also moved from Android to Apple not because I like iPhones better (I don’t, really), but because the years of security updates (versus maybe one or two, on Android) matters to me.
I simply live without most things. I have a ten year old laptop and a discount Android phone from about four years ago, and that’s it. No television, no console, no smart watch, no subscriptions to anything other than my internet connection which is also the slowest available.
I can stream YouTube, which I also use for music, I can do banking, I read the news. I don’t feel like I am missing out.
