That's true. Are there any other advantages to using Ubuntu over Raspberry Pi OS? Most of my projects run headless and take advantage of the GPIOs / built in camera. Does Ubuntu support those features well too?
Ubuntu does support using both the GPIOs and camera. I use Ubuntu other places so the advantage it gives me is familiarity. I can manage my RPi's just as I do my other systems. Also although there is a lot of Rsapberry Pi documentation available there is even more for Ubuntu and it applies to the RPi version.
