Apple used to be the "artists" computer. They catered to the art community of graphic designers, photogs & filmmakers. Their desktops were powerful and lasted years. But ever since the shift to iOS devices, Apple has neglected their original base. Long delays between desktop & laptop releases which end up being underpowered. Heck, the Mac Pro doesn't even have a 4k or 5k Cinema Display to go with it yet! As one of those artists who was an apple user before the iOS revolution, I miss those days when Apple used to pay more attention to its "power users".
The ironic thing is that now that the masses have switched to the iOS world, and many are not buying desktops or even laptops anymore...it would behoove Apple to rekindle it's love for the artists & power users and target their desktops & laptops to those groups once again.
