I am using my machine as a text editor, both in the literary sense, and programing sense. Though I find myself, using it as a communication machine, with people in this form of course, but also on Blue Dwarf, the cheapskates social media that runs on a raspberry pie 3b. I use it as a multi-media machine as well, I repaired some dell speakers/sub woofer combo, that matches with my dell monitor, So it works great for music and for DVD's that I am working on getting a bigger collection of.
All in all, if I was better able to get PDF files of my computer, or had a working printer, I would be using my Power Mac G4 for everything.
