Never have and never will understand what makes Apple so special. Except the MacBook, which is the best when you want to do serious graphic design.
That was the case with the Powerbook processor. Now that they are using Intel, and have been for years, it's a level field.
Also, the current Macbook Pro CPU is around 3 generations old and will hopefully be refreshed in the next 2 weeks.
The desktop devices are even worse, looking at the MacPro and MacMini.
The only place Apple's laptops have an advantage at the moment is in their price.
