I think Apple will continue to support the pro line if they're smart.
...
The 1 Mac Pro sold to 1 company that they STILL make a profit on (even if it's not as much as other macs) just sold 2-4 MacBooks.
I really, REALLY want to believe that. And in some cases it is true. But I don't see that as their plan.
I think they're planning that 1 iPhone sold (for a profit) will make a ton of profit from the App Store (a profit on code they didn't even have to write) will sell 2-4 MacBooks. And some iPads. Maybe an iMac if someone wants a desktop.
They want the transition from iPhone to iPad to MacBook to be as smooth as possible. That means taking some of the interface and options from the iPhone and putting them on the mac. Which I have no problem with whatsoever. I don't like it when they start to strip features out of Mac OSX (oh wait...). We've seen only a little of that so far.
Given that they sold more iDevices in 2011 than they have Macintosh computers since 1984, I don't think they're being dumb.
Apple has a long history of neglecting a former partner if they felt it was in their best interest.
They did it to resellers in the '80s when sales decided that if you couldn't sell 300,000 macs a year then you couldn't be an authorized reseller.
They did it to Microsoft in the '80s when Microsoft decided to launch Windows.
They did it to Adobe in the late '80's early '90's when they decided to write their own font software to avoid paying royalties.
They did it to Adobe when they denied flash on iDevices.
Most of those decisions were made when Steve Jobs was not running Apple.
But he isn't running now, either.
I never met him, but he seemed to be more interested in defining what was going to be popular tomorrow than preserving what was popular yesterday (at least with technology).
I'm not saying they're neglecting Pro users today, but it I'm also not feeling a lot of warm/fuzzy feelings.
I'm not going to ask if the Mac Pro is going away, but I will ask this:
Which do you think will be discontinued first:
A) Mac Pro
B) Mac Book Air/Pro
C) iPhone
D) iMac
