Legendary investor Peter Lynch's guiding principle has always been "invest in what you know." In other words, if you use Tide, buy Proctor and Gamble. If you use Rubbermaid, buy Newell.
When it comes to computers, I am a longtime Apple man. Although I had a Leading Edge 286 PC in the early '90s, I have used Macs since 1997. Even before Steve Jobs' return to the company, I found them easier to use.
If I had used Lynch's thinking and bought 100 shares of Apple stock this day in 1997, it would have set me back $403. Those same shares today would be worth $60,110. If I had spent $1,000 on Apple stock, I would now have $149,156.
Excuse me while I pour myself a drink.
