In my transition to #Linux , the main problem isnt finding decent software to start new things in, but file-format lock-in.
I've got years of work locked away in .ai files that are pretty much unreadable by anything other than Adobe Illustrator. They are a complete mess in Inkscape, and I'm not sure there's much to be done about it.
I should probably just declare them all done and live with the uneditable PDF versions.
