For me its honestly a ton of my work software (digital forensics), shit is too niche to be replaced by good FOSS options. Cellebrite, Magnet Axiom, etc. Autopsy is great and free and has a linux version but it simply cannot get the same level of data without a pretty nutty level of custom code.
And the biggest side effect of this is FUCKING WINDOWS. God I would replace this nightmare OS in a heartbeat if the aforementioned work software would make linux compatible versions. We have legitimately wasted 10k hours dealing with windows bullshit that would not be a problem in linux. Though im sure linux would take a different 10k for its own problems.
What about you guys? Doesn’t have to be work related, thats just the thorn in my side right now.
Onenote! I use it for school and work, and love the syncing capability and the flexibility in structuring and organizing my notes. I also like the keyboard shortcuts and the way it can dock to a side of the screen to keep the main content visible
Would https://anytype.io/ be a replacement? It’s very new so you might not have heard of it. It’s designed like Notion, but it might have everything you need.
If your needs are more simple, https://notesnook.com/ could be worth looking into.
Other FOSS options are Joplin and Logseq. I’m an Obsidian user myself; not FOSS but the storage format is completely open which is the most important to me.
