I've upgraded to Tahoe at 26.2, zero complaints from my side. Haven't had any runaway memory leaks or similar that were reported.

This. I have been a big (and loud) fan of M-series hardware from the beginning, but if Apple is going to keep making their software worse, I will find myself lingering on older generations that run Asahi Linux or going back to a traditional x86_64 laptop instead of buying into new generations.

The next macOS will be touch screen centric with elements getting bigger when you're close to touching them, rumors say. That being said, I run Tahoe and it works perfectly fine to me, I am not sure what issues people have with it. Sure, some corner radii aren't exactly the same but I honestly couldn't give less of a shit as long as it runs the programs I need.

I moved away from mac because of the OS and couldn't be happier. The hardware may be great but non-Apple hardware is fine too, and Linux is significantly better experience than MacOS these days.

Yeah this is a real issue with these new Macs. I would wait until macOS 27 to see the direction Apple takes.

Just yesterday, my colleague's mac Time Machine couldn't recover backup and they had to reinstall everything.

But I think this predates Tahoe.
