On December 11, the only known surviving Apple I computer personally sold by Steve Jobs -- out of his parents' garage in 1976 -- will be offered at auction. The auctioneer, Christie's, estimates a sale price of between $400,000 and $600,000 -- but just last week, the Henry Ford Museum bought a similar Apple I at auction for $905,000, and that particular computer lacked documentation tying it directly to Steve Jobs. We wouldn't be surprised if this Apple I (which is still in fully working order, incidentally) sells for over $1 million, making it by far the most expensive computer relic in the world.
