Apple's CEO Steve Jobs will open the company's Worldwide Developers Conference (WWDC) by having an informal discussion with developers on Monday, May 21.

The WWDC - running from May 21 to 25, and held at the San Jose Convention Center - will focus on Mac OS X.

There will be over 100 in-depth technical sessions at the five-day event, plus hands-on Mac OS X labs from Apple engineers and technology experts.

An Exhibitor Fair will display the latest development tools and products. Contestants in the Apple Design Awards will be judged for innovation, use of Apple technologies, and exciting product entries into the Mac OS X market.

Discounts on the $1,595 price tag for the five days are available to Apple Developer Connection Premier and Select members that book early.
