I work in web and educational design and we always have to keep accessibility in mind. It does limit the type of design we can do though, so it can be a bit frustrating as a designer. On my end I try to get the AA accessibility score, it's a good middle ground. I make sure to have good contrasts in my Headings, colours, add desciptions to images etc.
Yeah, as a designer I'm a mac user on my main work machine. A decade ago I installed some version of linux to revive and old laptop and it was... Ok. But I recently got a steamdeck with steamOS and I really love the look and customization of desktop mode, which made me look into different linux distros, comparing interfaces and it's true some of them look pretty cool. I think the main thing is to set it up as simple or as complicated as you need, the option to work without all the windows or macos bloat.
Great concept!
