Noticed this petition about adopting EVE to more operating systems. This topic has often been discussed here at CCP but it always boils down to were we should focus our efforts, i.e. should we port to Mac and/or Linux or concentrate on making existing platform even smoother.
Nothing would be done until after Shiva of course, I would still be interested to hear what you think.
There is a thread at the EVE Online forums regarding this issue.
