I kept my old laptop (bought in 2007) alive for quite a while too. But last year I finally retired it. I also used archlinux 32 which worked fine for a while. But at some point the breakages really got too bad. I was using xfce4. For a while the xfce4-terminal was broken and would not start. That has the easy workaround of using xterm instead. But there were more breakages and it just started taking too much time. Quite a bit of software is ditching, or has ditched, 32-bit support.
