> Is it just "because Apple"?
To some extent yes - Jobs built a company that was less about innovation and more about polishing and packaging existing tech for the masses. This isn't bad - Apple has made some great stuff, and they have innovated some, but a lot of the innovation is in UX not tech.
Things apple "invented" that had been around for a while:
* the mouse
* the GUI
* MP3 players
* the smart phone
* the tablet
* virtual desktops
* video calls
And plenty more I've since forgotten. We used to joke about Steve Jobs' Reality Distortion Field in reference to this phenomenon.
