How did this happen? Simple. The OS wars were a red herring. It's the hardware, stupid. It was the iPod that saved Apple, not OS X. But OS X was very successful in further destroying Microsoft's reputation. Just think back to the "Get a mac" ads. Sony has also fallen by the wayside. Even its venerable Walkman brand is dead.
In 10 years, who will be #1? Any thoughts? My guess would be a firm like Samsung.
