I used ThinkPad X32 (2004) with 768MB RAM as primary laptop until around 2015 (I switched to X200s because I got one for essentially free, not because the X32 could not keep up) and it was certainly usable for both development work and web browsing including youtube and social media (today it is not). On a similar note our Logistics Manager had used T42 with Windows 7 on daily basis as his only work computer well into second half of 2018. Coincidentally just today I had repurposed that particular T42 to serve as host for various industrial automation related configuration tools.
