When PlayStation 3 was launched in 2006, Sony promised users that they are able to install Linux as an alternative operating system because of its "other OS" feature; which is partially the reason why some users purchased the console. However, when the PS3 Slim was released and removed the support for the said feature back in 2010, it caused a lot of grumbling from the Linux community and a class-action lawsuit was filed against Sony.
Today, after six years of grumbling and outrage; Sony finally agreed to pay millions and millions of people who purchased the old version of the console. Sony will be paying up to $55 to whoever purchased the old version of the console within November 1, 2006 to April 1, 2010 and to be able to get the full $55, the owner must supply a proof of purchase of the console and proof of use of the feature "other OS". PS3 owners can also receive $9 if they are able to provide a proof of purchase and clear evidence that the reason why they bought the console is because of the feature and how they intended to use the feature.
Based from a post in Ars Techinica, the following are acceptable proof that users used the feature "other OS":
a) proof of purchase before April 1, 2010 of a version of Linux that is compatible with and was installed on your Fat PS3;
(b) proof that you downloaded a version of Linux that was compatible with and was installed on your Fat PS3 prior to April 1, 2010;
(c) a screenshot (or picture) showing Linux operating on your Fat PS3;
(d) a screenshot (or picture) showing that a portion of your Fat PS3 hard drive is still formatted for the Other OS with Linux installed;
(e) proof that you communicated with SCEA or a third party before December 31, 2010, to discuss your use of the Other OS or your concerns about Update 3.21, for example, copies of an email from you or a message that you posted on a message board that discusses your use of the Other OS functionality or Linux on the Fat PS3; or
(f) any other documentary proof you may have that shows that you used the Other OS functionality before April 1, 2010 that the Settlement Administrator determines to be valid.
