Apparently Valve boss Gabe Newell thinks the PS3 needs to be more of an open platform, drawing a comparison to Apple's Mac platform. In an interview with 5BY5.TV, he said he would like to see the PS3 be 'open like a Mac' instead of being 'more closed like a Gamecube.' 'Platform investments, like the Mac, are difficult because you have to be aware of what direction that platform is moving,' Newell said, referring to the firm's recent move onto Macs with its titles and distribution service Steam. 'We need to target platforms that do a better job of looking like where we want to be in a few years.'
