No Linux Support for GOG in the Foreseeable Future

Talking with Destructoid, Trevor Longino, the head of PR and Marketing for GOG.com, explained why the gaming store is unlikely to support Linux in the foreseeable future:
"For every game we release we provide a money-back guarantee: if we can't get the game working on the customer's computer with the help of our support team, we return the money. The architecture of Linux with many common distros, each of them updating fairly often, makes it incredibly challenging for any digital distribution company to be able to properly test the game in question, and then provide support for the release -- all of which our users are accustomed to."

Hopefully this will change in the future, especially considering there aren't a lot of options for Linux users right now, but admittedly, going from Longino's answer, that doesn't sound too likely.
