>Modern exploit mitigations
>OS updates
Good luck with modern intel exploits there, and I'm running OpenBSD 7.6 on an Atom n270 nebook like a champion. Power? Maybe a bit high for a machine from late 2000's, but is not so bad compared to a current powerhouse as a desktop.
I can play 720p video with no JS needed at all (mpv+yt-dlp), chat with Jabber/IRC/telegram, some of them over Bitlbee. I have locally curated playlists and music from both Jamendo and Internet Archive.
I can comment on both HN and Mastodon with https://brutaldon.org
I can program in AWK, C and Go. I can plot stuff faster with AWK+GNUplot than most people battling with CUDA, Python and months of GPU usage drawing more power
for a mundane task than a quality beef restaurant in a month.
I have several services routed from the web to Gopher, even Internet Archive.
I can read the news using a laugable bandwidth and CPU on the remote servers.
The average desktop today uses far more power with local and remote services in a month than my machine and the Gopher servers over a year.
