Would you pay $20 for a Linux desktop? I would, and in fact, I regularly choose to pay more than that when I download free software! The reason I do this is that open source is worth it. For a copy of Elementary OS, US$ 20 happens to be the default asking price (you can download it for $1 or even $0 if you can’t afford anything more). What you get in return is an excellent and heavily curated distribution that ships with its own Pantheon desktop design.
