Macintosh users have been known to be so loyal, that their relationship with the MAC can be called almost religious. Apple introduced to the world the Macintosh. It was the first of its kind. It was the first to have icons (on desktop) and a mouse.
The first Mac sold in 1976 was built in a garage. Although Mac was the pioneer back then, today it has only 3-5% of the market. Ted Friedman of the Georgia State University says this is because others come in and copy Mac and then underprice it.
In a legal fight which took place in the 90's, Apple accused Microsoft of copying Macintosh interfaces in Windows. The case was settled out of court in 1997. Source
