The Apple I's built-in computer terminal circuitry was distinctive. All one needed was a keyboard and an inexpensive television set. Competing machines such as the Altair 8800 generally were programmed with front-mounted toggle switches and used indicator lights (red LEDs, most commonly) for output, and had to be extended with separate hardware to allow connection to a computer terminal or a teletypewriter machine. This made the Apple I an innovative machine for its day. In April 1977 the price was dropped to $475. It continued to be sold through August 1977, despite the introduction of the Apple II in April 1977, which began shipping in June of that year. Apple had dropped the Apple 1 from its price list by October 1977, officially discontinuing it.
As of 2008, an estimated 30 to 50 Apple I computers are still known to exist, making it a very rare collector's item. An Apple I reportedly sold for $50,000 at auction in 1999; however, a more typical price for an Apple I is in the $14,000–$16,000 range." (Wikipedia)
