and a bunch of “professional” apps.
It is in fact a bunch of pre-installed free software. I like Zorin, but Zorin Pro just seems like a way to trick businesses into paying for the distro. I guess having access to a support team is nice, but otherwise it's not worth it at all.

The Linux phones that exist today (including Pine Phone) are more like early dev kits. They have really weak specs, are incredibly buggy, lack all sorts of features you'd expect, and I'm not totally sure if you can even make calls through them because phone carriers require a verified device and proprietary tech to work.
There are efforts to get things in order but these will take maybe 10 years at this rate.
