Just looks at what apple has been doing over the last few years. Clearly they are moving away from their core pro users. It's only a matter of time before they pull the plug. Although the iMac core i7 is so fast, it would be more than fast enough for most pro users except for high end video and 3d rendering. Paired with a Thunderbolt raid, it would be cheaper and close in performance.
It seems Apple has forgotten who got them to where they are today. If pros where not so cult-ish mac fans, then they would of died in the early 90's.
Well, shocking thought.... Apple never wanted Pro users anyway. Steve certainly didn't.
His original idea was for the GUI really, the hardware it ran on was irrelevant. He wanted to make an easy to use computer, and I doubt that was really for "Pro" users. Steve wanted to make computing easy and accessible for the masses.....
It was only the price that gave it that "Pro" niche. I have a real feeling the Mac classis was supposed to be the iMac. Small, simple, computer for everybody. It was only post steve that the hardware turned into Quardras and Powermacs and beige boxes and when you don't sell big volumes then high priced high end, high margin products like "Pro" stuff matters.
Fast forward, steve's come and gone, iMacs, iBooks, ultraportables, iPods and finally iPads.... steve has finally realized his original vision to change the world by making computing simple and a part of everyone's life..... "Pro" users don't fit into this vision... and short of the price, Pro users didn't fit into Steve and his Mac Classic style vision either.
The biggest legacy from Mac OS X, the switch to intel and Apple's choice of standards support in the iPhone and pad gave rise to one simple thing. Platform independence.
