itwbennett writes: Apple shares inched over $300 for the first time Wednesday, nearly 30 years after Apple's initial public offering in December 1980. But it hasn't been a steady climb. In fact, says blogger Chris Nurney, 'Apple's stock history can be divided into two clear periods — the early years, from the IPO through Steve Jobs's long absence from the company after losing a power struggle in 1985, and the modern Jobs era, which began on September 16, 1997.' The bottom line: 'If you had purchased $10,000 of Apple stock the same month that Jobs again began leading the company, your shares would be worth $554,000 today. Not a bad return on the investment.'
