There are quite a few types of Apple "Fanboys" -
1. There is the ones you mentioned - those who stand by Apple because of the great experience they had.
2. There are those who got burned a few times, but are well situated into the Apple Ecosystem that they are a little more patient for launch day products. They are excited to try it out, but they aren't crazy. These people don't stand in lines.
3. There are those who are excited by whatever Apple makes and they order online because that's very convenient to them. They dislike the idea of standing in line for weeks to get a launch day device.
4. There are those who are so excited and impatient to get their hands on a launch day Apple device that they will camp outside stores to get their Apple product.
5. There are those who swear by Apple. These people have every single quality available in the world. They launch brutal mind attacks on anyone (yes even fellow Apple Fanboys) who dare criticize Apple. These folks are the only Apple Fanboys that can't see beyond Apple. They would prefer having every Apple competitor die out simply because they think that Apple is the only company that can innovate. They go by various names such as Appleians, or Applews, or Applim, or Appleu, or Appleist. Indeed, Appleism is their primary belief. Even if Apple screws them over, they think of it as Apple's mercy on them for they are insignificant compared to Apple. They troll anything related to Apple's competitor and they trash everyone. If Apple released a product called *****, which was literally a solidified version of Tim Cook's ****, they would buy it and place it as a center piece in their house for all to bathe in its vast glory.
6. There are those who swear by Apple but aren't crazy like #5. They aren't used to Android devices and they put up a good argument.
7. Finally, these are the underground, secretive Apple fanboys. They hang around parking lots and stake out stores because they love the smell of freshly bought Apple products. They need some money and they are too much in love with Apple to get a real job, so they steal from their fellow fanboys so they can stay connected with Apple.
These are the famed 7 types of Apple Fanboys. They go by various names, but in the end - majority of them are pretty nice. You just have to worry about #5 and #7, because #5s are very similar in nature to say Justin Bieber fans.
