From June 11 to 15 it’s all about the Mac developer community in San Francisco under the warm sun of California: At the Apple’s World Wide Developer Conference the whole hardware and software developer community is gathering to get and exchange Mac first-hand insights.
The company is running a scholarship program for students developing for the Mac - 500 students will get scholarships to enter the conference for free (a US $ 1,559 $ value). But coming to California has to be arranged by the student him- or herself.
Application deadline is March 19, 2007 - so, if you are a student and want to join the conference, apply now.
