Does anyone know of any MipsLE/Mips64LE systems in the wild?

IIRC, SixOS is built for MIPS systems and runs quite well on them with lots of VERY futuristic options (the most impressive he calls “ownerboot”).

And now that I have made the post I got some search results:

1. Routers apparently still use MIPS
2. https://www.linuxdoc.org/HOWTO/MIPS-HOWTO-3.html has some MIPS systems you can run Linux on.

If you want to share anything about MIPS though please feel free to comment, I would interest me greatly what the rest of you have to say.

I think the phones at my university are MIPS. VoIP phones.

There were two or three MIPS Android tablets long time ag, at the time of Android 5. Now Android does not have MIPS support anymore.

Some older routers use MIPS architecture.

Edgerouters x use MIPS. Compiled some go code for mips to run on it a few years back.

MIPS is special purpose, unlike something like ARM. You'll find them a lot in carrier-grade comms equipment, electrical, mechanical...etc. They aren't meant for general consumption.
