Apple Vice President of Worldwide Developer Relations Ron Okamoto mentions that, in the three years since the introduction of OS X, 'people who have experience in those areas are showing a great interest in our OS. We're seeing a lot of first timers. It's really impressive.' The company said it has recently surpassed the 300,000 member threshold of registered developers. Apparently, the increase in enterprise code writers has prompted Apple to add more sessions focusing on enterprise and IT to its upcoming Worldwide Developers Conference."
