What's the implication of the new graphs from @asymco for your studies, investment and work?

I just listened to Horace Dediu telling the story behind his wonderful new graphs on the IT industry, published on http://asymco.com. Listening, while looking at the graphs on my iPad here are some immature thoughts on what the implications for these graphs could have for me and others:

1. What platform should I study, PC or mobile?

2. Which company should I buy from or invest time and money on?

3. Which company could I trust in the long run?

These graphs covers the time from 1975 - 2012. That's 37 years, and really my whole marriage and my whole career. One could really memorize the past looking at these graphic stories!

Personally I was late to bet on Apple. It's only two years since I made the transition to Mac. The iPhone 4S is the fourth mobile from Apple. I was however selling Macs a year in the early -90. 

The last graph somewhat yealls at me that the only company that have lived through the whole IT era, and that has relevance to individuals are Apple.

I'm really looking forward to Apple's educational event which start in an hour, and the disclosure of their financials the 24th at 23:00 local time!

I keep you posted!
