Pretty decent, but there’s a few things I think should be improved:
Logos !!!
Instead of having a chain of distros as an answer, make a nice group and don’t point towards any one of them. I’m still trying to figure out if you have some sort of ranking going on.
The split after “Windows or Mac? -> Mac -> <similar> or <similar and user friendly>” is weird and should probably be a question and differently phrased.
Immutability is misspelled and not explained. The gradient also makes it looks more special than the others (while it’s just a difference). Maybe an asterisk with an explanation at the bottom would be better for this.
At one point you use “Please” instead of “Yes”. I understand the joke, but people who could actually use this flowchart might not.
SteamOS is not a viable distro choice. (For now at least) I would suggest removing it until it actually becomes one.
“Are you a developer” has 4 answers but could be split into “Yes” and “No” with their own GPU questions.
White on yellow/orange is hard to read.
White on pink is readable but could be made easier to read.
Maybe a better font would great too
You could also add some Lemmy/Reddit/forum URLs where users could get Linux help.
You could also add some information like “Just looking for a Linux laptop? Buy System76” or something (I’m not up to date with decent Linux laptop vendors)
You are open to critique so I hope you don’t mind this many points.
One addition: On the right, “A computer from this decade?” — I think this can easily be widened to “A computer older than 15 years?” (swapping “yes” & “no”, of course). The laptop on my lap is exactly 10 years old, wasn’t high end back then, and runs OpenSUSE with KDE easily. Well, in all fairness, it’s now got 12 GB RAM, but that’s mostly for development purposes. Perhaps one could go directly ask: 8 or more GB of RAM?
