I have played guitar for 33 years and when the internet first came around to the masses, I looked for guitar stuff and found nothing of real worth. Even today, while the guitar sites have improved, there is no guitar equivalent to macrumors.com for Apple fans.
Part of the reason for this is that there are mostly semi-enthusiastic guitar players among the groups worldwide, where as Apple fans are almost universally very enthusiastic. Many a person, if not most, either get a guitar and never learn or tire of it when it gets too hard. And many once enthusiastic guitar players grow out of it thinking it was a juvenile pastime. Macs are different as most people who get them, at any age, use them and rarely leave the platform.
The only brand I have read about that has the same loyalty as Apple are Mazda (Miata owners) and Harley Davidson owners, and they still pale in comparison to Apple fans who are extremely interested in the latest developments at Cupertino. I don't see Miata or Harley owners wondering "what's next?" with the vehicle's evolution in next year's models. Usually, somebody who has a Harley or Miata are happy with what they have and call it a day. Many an Apple fan, give out great praise for developments like a less expensive iPhone with same features and breathe out flames of fire when Apple lets their customers down by not putting firewire into the new Macbook. There is no group so passionate about a product out there, short of a cult, like Apple fans, and Apple has, maybe justifiably been called a cult.

And if there was a stronger word than cult, then some may feel Apple applies for that label.
