5 of the most expensive Apple products ever

The legal document that started the most valuable company is apparently worth as much as 8,000 iPhones. That's how much auction house Sotheby's sold Apple's founding documents for in December.

Signed by co-founders Steve Jobs, Steve Wozniak and Ron Wayne on April 1, 1976, the three-page agreement set up the foundation for the Apple Computer Co. (AAPL), giving Jobs and Wozniak each 45% of the company and Wayne the remaining 10%. Just 11 days later, Wayne withdrew and forfeited the ownership.

Bidding for the papers began at $70,000 and was estimated to go for $100,000 to $150,000. The final price fetched more than 10 times that, when Eduardo Cisneros, a media and entertainment mogul, submitted the winning bid.
