10 stupidest tech company blunders

I recently read an interesting article in PCWorld.com entitled, "The 10 Stupidest Tech Company Blunders.” While it’s easy to sit back and laugh at how dumb these decisions look now, I like to look at lists like this and think, “What mistakes did they make and how can I avoid them?”

In a few of these examples, but most notably the RIAA example, I see a valuable business lesson: When the world changes, don’t fight to keep it the same way—you’ll lose every time. Instead, figure out how to adapt to the change and capitalize on it.

How about you? Do you see any valuable business lessons in all of these mistakes? I'd love to hear them.
