1. Born in San Francisco on February 24, 1955 to Abdulfattah John Jandali and Joanne Schieble, Steven Paul Jobs was adopted by Mountain View couple Paul and Clara. Jobs only met his biological sister Mona Simpson when he was 27, but the pair became close quickly. "She's one of my best friends in the world," Jobs said. "I call her and talk to her every couple of days.'' Simpsons writer Richard Appel later married Mona and used her name for Homer's mother.
2. Jobs was educated at Cupertino Junior High, Homestead High and enrolled at Reed College in Portland, but dropped out after one semester, giving hope to college dropouts everywhere. On his return to California, he joined the Homebrew Computer Club with Steve Wozniak, who he had met as a summer employee at Hewlett-Packard.
4. The first Apple Computer (later dubbed the Apple I), was just a circuit board with around 60 chips and 4KB of memory. Users had to add their own case, power supply, switches, keyboards and display. It went on sale in July 1976 for the princely sum of $666.66. The fifty or so Apple Is that still exist swap hands for tens of thousands of dollars today.
5. In 1983, Jobs headhunted Pepsi-Cola president John Sculley to be Apple's CEO with the immortal and prescient words "Do you want to sell sugar water for the rest of your life, or do you want to come with me and change the world?"
6. After the commercial failure of the Lisa (allegedly named after Jobs's daughter) and qualified success of the Macintosh, Sculley and Jobs fell out and Jobs was edged out of the company. He went on to fund NeXT Computer.
7. NeXT was bought by Apple in December 1996, bringing Jobs back home. The change in Apple's fortunes after his return is difficult to overstate, but as an example: If you bought an Apple PowerBook G3 250 in 1997, it would have set you back a hefty $5,700. If you had invested that cash in Apple stock at the same time instead, its value would have rocketed to $330,563 by 2010.
8. Some more numbers: Over 300 million iPods have been sold since its launch ten years ago. Chief exec Tim Cook noted that it took Sony 30 years to sell just 220,000 Walkmans. More than 100 million iPhones were sold by March this year and 15 million iPads. By last February, the iTunes store had sold over 10 billion songs. By July this year, a whopping 15 billion apps had been downloaded.
10. Steve's casual CEO styling of classic black mock turtleneck, blue Levi's 501s and sneakers became almost as iconic as some of his products. Some claim that he wore the same pair of 501s for years, others suggest that he owned over a 100 pairs. A website called Steve's Outfit exists so you can copy Steve's look.
