I find FOMO strange about a lot of things on so many levels, but operating systems take the cake. Truly. It's just a GUI you launch stuff from, for Christ's sake. What's to miss?
I haven't upgraded the two PCs I was offered Win11 in (they are AMD-based so it's not wise to do anyway right now) and I do not plan to upgrade the Intel-based one either.
It seems like we are back to the SP1 days with Win11, it's clearly an unfinished product. I would have been furious if it offered anything of great importance, but since it doesn't, I give it a shrug at best. More important things to do anyway than worry about Windows in Q4.
