I've just 'upgraded' my Cosmo from Debian to UBPorts using instructions from oesf.org.
Here is the link to the thread https://www.oesf.org/forum/index.php?topic=36413.0
Seems solid and snappy. I haven't tested telephony yet (sim card in PinePhone, also on UBPorts), but I will be testing soon.
See photo of UBPorts running on both PinePhone and Planet Cosmo, very groovy.

Thanks for that. Yeah, probably right, I reckon the photo pushed the spam filter over the edge. I've tried to repost without the picture but no go, so I reckon maybe my card is marked until I build up a bit of history. Shame really, it was a very groovy photo of UBPorts running on a PinePhone and Planet Cosmo side by side, very convergent.

I'm getting this same message when trying to post a reply on a thread about the Cosmo Communicator. I'm new here, and also tried uploading a photo in my post, I don't know if that's significant.

Hi,
Just got here, running UBPorts on PinePhone and Planet Cosmo.

voice calls all good on 2degrees + vodafonenz, sms sending but not receiving, probably an apn setting I need to resolve on the Cosmo, your mileage may vary as they say, based on country and carrier, to be continued.
It basically works, very well. I need to fiddle with a few things, but this is why we are here.
UBports is such a nice place to be.

I came across this github page via another forum, describing terminal commands to control the LED lighting on the Cosmo (and Gemini), including the keyboard backlighting on the Cosmo.

Originally for Debian but seems to work perfectly on UBports, I have only tried the kb element on my Cosmo as the external bells and whistles on mine got damaged in a fall , I thought somebody else might find it useful too. I have absolutely no idea how to turn this into keyboard shortcuts, I'm just an electrical engineer with a groovy mobile, but maybe someone with coding skills would like to have a play?

"keyboard will be laptop equal"

I can vouch for the Planet keyboard having run a Cosmo as my daily driver for the last 12months, that Martin Riddiford chap clearly knows what he's doing. I can only speak from my own experience, mine needed to bed in initially, but now it's quicker than me. Some people have reported some issues, maybe related to early production issues or expectations, it isn't a real 'real' mechanical keyboard after all. Have a look at oesf.org for info and other experience. Personally I am more than happy with mine.

On a desk typing 'properly', in the passenger seat with it on my lap, or thumb typing stood up or reclining on the sofa, it is just so nice. Out of the pocket, instant on, no farting around with a separate bluetooth keyboard, it makes you productive, you look forward to using it. Pecking away at a virtual character behind a flat untactile piece of glass like some demented seagull looking through the window of the local fish and chip shop just feels so wrong now. How did this ever become the norm? I also genuinely even prefer it to my 'real' laptop, which is only a little 11" one, but the keyboard seems so vast and so much effort compared to my Cossie. I came to Planet for the possibility of Linux, but definitely stayed there for the keyboard. UBPorts on Planet Cosmo is the best.

I am watching the Astro Glide or Slide keenly, as I watched the Cosmo and the Gemini before it, it's nice to have a choice. I won't be buying one just now, simply because I am happy with my Cosmo, but if I could justify it I would be in at the drop of a hat. Unfortunately, if I ordered yet another gadget in the current climate or whatever, my loved one would smother me in my sleep.

@sven
I've revised my post to include a link to the thread on oesf with the instructiion.

@AppLee
It was the old and unlocked thread I was trying to post on. Silly spam filter was blocking every attempt. I just tried again and it accepted the post.
