I haven’t tried it, but the live kernel updates feature is what intrigues me the most.

I don’t see why one would bother. I’m really not worried about a state actor or major hacking collective pwning a firewalled laptop, and if I WAS Ubuntu wouldn’t be my choice of distro.

free security updates are a win of course

No. I upgrade my Ubuntus before they go EOL so I don’t need ESM.

Most places that want ESM do so because they can’t get away from EOL versions. I refuse to get stuck in that swamp myself, so I run LTS and migrate/rebuild them when necessary.

I’m running Ubuntu on a server. I’ve enabled the free Ubuntu Pro subscription to get ESM patches for the universe repository. Not sure if it really matters, but better safe than sorry.

I’ve tried it. Can’t really see much difference from not using it. As others have said, being a personal user you’re not much of a target - being smart about what you run on your computer has much more of an effect on security.

In the future I probably won’t bother

I have enabled this on my private machine, because it’s free and it was asking so nicely.

I don’t have the same patches on servers at work.

I do. I upgrade before the major release goes out of support, so no I don’t get much from it, but I do still get patches from it occasionally. Iirc they released an imagemagick patch before upstream did
