Re: Too much choice?
Actually, there is only one Linux. That would be the kernel.
When you take that kernel and add the packages that you, personally, need/want, you have a distro. Ideally, all of us should have our own individualized distro ... unless you actually know a person who uses a computer EXACTLY the same way that you do, of course.
So no, there is not "too much choice" out there ... if anything, there is not enough.
At this stage of the game, we should be moving away from marching in lock-step, all using the exact same set of tools, and instead customizing systems to suit each and every user. (For example, MeDearOldMum has no need for the kernel source and most dev tools, so I don't install that stuff for her ... the rest of her system is similarly customized).
Sadly, that would be hard ... and people like the easy way out. So they just use what is given to them, without bothering to think about it. And so many/most are stuck with the systemd-cancer, for example. Including most down-stream distributions, which makes it look like there are too many distros, even though there are really only a few.
