Linux on all of my main machines, so I'm grabbing the popcorn. Got LTSC for all the remaining Windows use cases: VMs, beater laptop for Windows-only stuff, and a couple of computers from family.
Most of my friends replace their computers quite frequently, so they're living blissfully unaware on Windows 11 or MacOS. The ones who do have older laptops tend to be tech-savvy enough to have figured out LTSC or Linux themselves. On one occasion, a good friend of mine had an old iMac that wasn't getting updates anymore, so I installed Debian and themed XFCE to look like MacOS, taught them the basics, and they were impressed with the result.
As for family, they're usually very happy with the Linux Mint Debian Edition that I install for them, but some I know just won't use the computer if it doesn't have their familiar Windows-specific software, so I get them started with LTSC.
I frankly have an excess of unused hardware that's piling up, which won't be helped by my access to a good source of e-waste. Old computers have already been trickling in, but I'm excited to see what's next now that the Oct 14 date has come.
