If we look at Mac operating system, for example, it is such an OS that sets the bar and is not only for the functionality but also for the transitions of the users from one operating system to the next one. The traditional music player was defined again by the iPod of Apple and so is the case with iTunes which redefined the spread of music all over.

As with any company, mistakes are a must during its growth and success, so is the case with Apple Inc. There had been almost a dozen mistakes that are made by Apple. Almost everyone is familiar with the Lisa`s story which was a replacement for the series II and III of Apple which was ended as a total mess which didn`t work out the way it was supposed to be. But most people do not know about the Copland operating system and about the Mac clone disaster.
