Two months with Linux as my daily PC driver. I do not regret it.
I have walked from Microsoft Windows via Apple macOS to LMDE Linux Mint Debian Edition.
Most of my computer software, operating system as well as applications, are free and open source software.
@hehemrin My path from Windows 20 years ago was moving all my workflows to FOSS apps and then shifting the data to a new machine running Linux. Never looked back.
@WT4U Thanks, good to hear. I think one challenge with FOSS is that people in general needs income and it should be possible to do that in sw jobs, and I believe a sustainable business model/income is an issue for FOSS jobs, but I don't really know. One big challenge for me was photos esp catalog, migrate from Adobe Photoshop Elements to digiKam, in the end data migration worked quite well but needed preparation, reading and testing (which I completed on macOS well before switching OS).
@WT4U A major reason went for digiKam is the people/face-tagging which DarkTable lacks. Although digiKam can develop raw, I have added RawTherapee. I also have GIMP, not used so much yet. DarkTable is defenitely on my potential list. One non-free photo related sw I like very much is VueScan - and I am not aware of any corresponding FOSS that is close to its capabilities.
@hehemrin I use a mix of DarkTable and GIMP for images, but there are always a few nifty features I'd like to add.
If companies contributed a significant fraction of what they're paying in Adobe subscriptions to support open source development it would be they'd get a much better ROI. Paying devs to keep re-inventing proprietary solutions to the same problems smacks of busywork. There are better uses for the talent.
