I take it that they only sell Steam keys for the titles without the "DRM FREE" icon? This has confused me in the past. As a Linux user, I'm a big fan of Humble because they actually pay for new game ports, so it is often the case that a Linux version debuts in a Humble Bundle. But with Linux games getting mainstream and HB increasingly becoming a Steam reseller I would much rather see GOG.com introduce Linux as a platform (and also maybe hire some guys to look after Wine status of games).
