Things that intrigue me:
- For photos, darktable is surprisingly good. I think this was my biggest single surprise, being a Lightroom user.
- GIMP was always great and now it's even better.
- LibreOffice is good enough that I can live on it just fine. I do miss Keynote, but it's not a showstopper.
- Dia is good enough for diagrams, though I miss OmniGraffle.
- Notice how there aren't any Windows apps I miss. There are Mac apps I miss (Keynote and OmniGraffle).
- Anything involving the web just works.
- Suspend/resume on my Linux laptop works better than suspend/resume on Windows, but not as good as what you get on Apple M hardware.
- Battery life on my Linux laptop is better than on Windows, almost entirely because Windows wakes the laptop up while it's suspended, so if you close the Windows laptop and carry it around unplugged, you'll find that the battery is totally drained after some number of hours. Linux doesn't have this problem.
- Development workflow is amazing. I'd rather program on Linux than anything else.
- The lack of crapware and nagware is so amazing.
