Apple should be worried also... the market is saturated, growth is slowing, technology is turning stagnant.
You Apple fans can celebrate today, but tomorrow it will be your turn to cut losses.
Mark my words.
That's such a general statement that'll hold true regardless of what side you're on.
This is nothing new. All technology stagnate/saturate and move on to something new. Just like the shift from the early desktop pc to laptops to mp3 players and now the smartphone. Take a wild guess, how much profit do you think Apple is making thru ipods relative to 5yrs ago?
However, if anything Apple tends to do better at adopting to new technologies if not pioneering or reinventing them.
