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

Just a spicy tidbit from a radiant consumer world.

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.
