This is my plan going forward. Linux wasn’t on my radar when I bought my laptop (and my PC but that’s a different story about just being scared to try since I use it for work and I’m not convinced Linux has comparable software I need).
I got a wicked sale on a Samsung Galaxy Book 3 Ultra, and of course a few months after I started cutting BIg Tech out of my life (I was an idiot for buying Samsung to begin with but too late now haha). No more Meta, Amazon, or Google accounts or devices for me, and all I have left of Big Tech is Microsoft on my laptop and PC. I tried Mint as my first Linux attempt, and put it on my Samsung laptop. It…didn’t play well unfortunately. I’ve read Bazzite may work better but haven’t tried it yet.
Moral of the story, you nailed it. Going forward every bit of tech I buy will be vetted for FOSS support first.
As far as my main PC, I’m a freelance voice actor, artist, and musician. My main concern is recording software and to a lesser extent, art software (I’ve tried Inkscape, but it’s a hard transition from photoshop). For recording I really don’t like Reaper, and I use Audition (I know, Adobe, haha) and Cubase for music which unfortunately doesn’t have a Linux option.
As per the laptop, it had some standard driver issues which were no big deal but apparently Mint doesn’t play well with Nvidia graphics cards. The webcam didn’t work but that’s a semingly standard issue. The biggest thing was Samsung chips and such from what I read really don’t play well with Linux, or at least Mint.
