RedditArs Technica had an article about it recently:

Old reddit is now forcing an account.

Depending on the controller board yes. Lightburn is more than control though, it’s also design/preparation/GRBL gcode generation for the job.
SeattleNo. You have a semi (mostly) closed loop system. The user failure is the lack of knowledge of not properly sealing the loop or insulating it.
Think of it this way, if your external door is cracked a little and opened of its own accord with another open open window causing it to open that is negative pressure. Now imagine it on a lower airflow restriction pulling air into the area you are trying to cool through all of the natural air leaks in your dwelling. You will end up heating the air you are trying to cool causing the single hose to work harder while pulling more hot air to cool.
With dual hose you are localizing both input and exhaust air in a smaller area. With proper insulation or even just a blanket wrapped around both hoses, it makes it easier to maintain ambient air temps.
To anyone considering a portable single hose unit. Don’t.
Spend the extra on a dual hose portable and wrap the hoses with a blanket.
Single hose pulls hot air from the outside to cool the compressor which kind of defeats it’s purpose. Dual hose is a somewhat closed loop system where it pulls outside air with one hose to cool the compressor while exhausting the hot air out from another hose.
Seriously they are like $100 more and will save that in electricity bills over 1 hot summer easily.
You can also run klipper on them if you want network connectivity. Granted you need a raspberry pi to run klipper so there is that.
After running klipper on my Ratrigs I can’t even consider Marlin anymore. Modifying a config file and restarting is less painful than having to compile and flash a bin for every modification or update.
