I am a freelance computer technician working for small businesses and individuals. 99% of my customers are using Windows computers. The computer and laptop I use for my business run Linux Mint (Olivia-Cinnamon). I am a musician and have discovered the music writing program called MuseScore... awesome open source program for getting music on paper.
"This is a terrific app. It has many of the features of expensive non-open-source programs like Finale and Sibelius. I use it in Linux Mint and my daughter uses it in Windows 8."
