"In 2017, somewhere between getting my office and my website off-the-grid, I decided not to buy any more new laptops. Instead, I switched to a 2006 second-hand machine that I purchased for 50 euros. [...] I invested less than 150 euros. If my 2006 laptop runs for another 1.7 years it will have cost me only 26 euros per year. That’s more than 10 times less than the cost of my previous laptops."
