$&*&$#! Well I just discovered my late 2013 27” iMac did not make the Big Sur cut. How long does Apple support previous OS versions? A new iMac Pro would be nice, but not needed at the moment.

Typically about 7 years, so the cutoff is in line with that. It always sucks, but if I were you, I'd wait until Apple releases an ARM-based iMac. That'll run circles around your current machine.
I don't suffer from insanity, I enjoy every minute of it.

The usual hackers are trying to patch Big Sur to run on earlier Macs. I think they're taking longer than usual, not sure why.

Anyway though, your late-2013 iMac can run Big Sur without modification. If you have a fusion drive setup, that will experience a performance hit, but no other known issues.

You just need to bypass the installer blocks. Easiest way is to install to an external drive on a supported Mac, then boot your iMac from that drive.

I’m going to wait until the new iMacs are released. I’ll donate my current Mac to my mother. My last donation, 20” 2007, has been limping along on an external hard drive. The backlighting is starting to die. Hopefully it will last until the new ARM iMac arrives. She will be happy with the jump to a 27” screen.

How much of a drag is Big Sur going to be on my 2013 MBA? I upgraded from High Sierra to Mojave pretty soon after it came out and it turned the thing into a dog. It's gotten better (or my standards have dropped?) but I haven't bothered going to Catalina. Is Big Sur going to be more of a resource hog or will it be optimized for better performance?

I suppose I should double check for any 32 bit programs I'll lose access to if I ditch Mojave. The thing is mostly for web browsing and running various flavors of Windows in VirtualBox.

I’m still on Mojave on my MBP; it is still pretty snappy, what with the SSD and everything.

I didn’t go to High Sierra, basically because I didn’t see anything in it I “needed,” and it was almost certain to break some of the apps I still use from them olden days.

So what is the draw for Big Sur? “What’s in it for me?”
