So do I. But I cannot call those I see "modern".

Just a spicy tidbit from a radiant consumer world.
Server hardware is more conservative, of course.

Irrelevant. That new fancy ARM Mac is using UEFI too, or so they say.
Whatever Apple used then they used PowerPCs has historical value at best.

I do too, but really, if you have that M8 - do you run Linux on it? Or,
for instance, NetBSD?
OK, M8 is costly. Let's consider something cheaper and older, like T4 or T5.
I know one can get those on eBay, heck, someone still sells T2000s, T1s,
and even parts for E25Ks there.
Does it still run Solaris for a certain reason? Because those that I
see in my line of work definitely do.

It's possible, of course, to run something other than Solaris on both T
and M series (unsure about E series), I still have that LDOM running
kernel 4.1.12 just because I can, but it never grew up to anything
bigger than proof-of-concept.
