A virtual machine is the move, I’ve had a great experience with virt-manager. Strongly recommend debloating the windows VM if Microsoft is getting on your nerves. Here’s my go to software: https://github.com/raphire/win11debloat
Worksorks on both windows 10 & 11. It’ll allow you to remove telemetry, tracking, and even software Microsoft prevents you from uninstalling. I just can’t get it to remove Edge. But MentalOutlaw has a fantastic walk through of the process on his YT channel if you want some guidance with the debloating process.
Obsidian isn’t FOSS, but two fantastic replacements are Standard Notes and Notesnook.
A great paint option I don’t see listed is KolourPaint, plus Kdenlive for video editing. For audio editing, Tenacity is the better choice over Audacity. It’s an Audacity fork made after some questionable privacy policy changes.
CryptPad is an awesome Google Doc’s replacement, but Libre Office is actively working on their version too.
For your security section, adding some encryption software would be smart. Both VeraCrypt and Cryptomator are amazing. Also, Bitwarden/Vaultwarden are solid password manager alts for KeePassXC, with Vaultwarden being self hosted.
Here’s a great site for all sorts of Lemmy clients.
As far as Linux laptops go, System 76’s Darter Pro is also a solid choice. Tuxedo is probably System 76’s biggest competition, as they offer very comparable laptops. Their InfinityBook Pro is a great computer. Frameworks, Slimbook, and Star Labs are all also worth a mention.
