I'm thinking about completely removing non-free software from my life. What will I miss the most? Flash will be the killer, since some services I like use Flash, but oh well.
FOSS more than covers the scope of computing that I'm interested in. Text editing, compiling/debugging, and web browsing make up 99% of my computer time. I use Photoshop once a year maybe, MS Word even less than that. FOSS is not simply a software choice. It's a lifestyle.
