Pretty much.  I had three in live use as of 2020-01-01, one at home and
one at each of my workplaces.  For the last year-plus I've been 100%
WFH; one of the workplace machines has been recalled to home and the
other is still at the workplace in question, but turned off.

My fallback is to drag another one out of cold storage and put it into
use.  I've got two at home, one my hack-around-on spare and one the
work machine brought home I referred to above, and I've got more in
storage - enough to last me the rest of my probable life and then some,
at current failure rates.  (I haven't had many failures; the one I had
to let go didn't lose its magic smoke, just started failing, and
FRU-swapping led me to think the fault was on the motherboard.)

I'm more concerned about VSIMM failures.  I've got only the one 8M
VSIMM as far as I can recall, and only two (I think) 4M VSIMMs.  It's
not for nothing that I included "[t]wo 8M VSIMMs" when outlining what
could make a SS20 worth $200 to me elsewhere in this thread!
