A brief explanation why…
Ronald Wayne joined Steve Jobs and Steve Wozniak to found Apple on April 1, 1976. Wayne met Jobs at Atari and provided administrative oversight during Apple's first days but sold his shares less than two weeks with the company for $800 plus $1,500 a year later to forfeit any claims (around $9,000 today).
Among other personal reasons, Wayne backed out because he was concerned about the potential for creditors to seize his assets. All three partners assumed equal responsibility for the company’s debt, but Wayne was the only one with much to lose.
Had he kept his 10% stake in Apple, Wayne would reportedly be worth in excess of $60 billion, but when interviewed he has said he lives without regret and made the best decision with the information he had at the time. After leaving Apple he returned to Atari and has since retired to a mobile home park in Pahrump, Nevada where he sells stamps and rare coins.
The first Apple product Wayne owned was a gifted iPad 2.
