- Aging HFS+ file system.
- Lack of decent OpenGL 3.x / 4.x support
- Lackluster support of OpenCL (which Apple introduced)
- Mac OS X Server is a joke for most areas where you use a server OS.
- The Finder still fu... up in a semi-sporadic fashion while connecting network shares.
I bet, you have your own griefs to add to this list.
So finally, after looking at the software side we can wait for the other shoe to drop - i.e. the hardware side. I think the same signs we have seen on the software side can be observed on the hardware side.
Just think of:
- Trying to sell a Mac Mini as server hardware (ridiculous).
- Killing perfectly well working interfaces (Firewire) without a reasonable transition plan.
- The joke of a RAID Controller Apple is selling or the 2012 Mac Pro update.
- 10bit per Channel Output anyone? Hell, my SGI Octane is able to output RGBA 48 bit and this is ten year old hardware.
So my guess is, Apple will not really care much about the tiny Pro Hardware segment requirements. It's about money and they want to sell their new Pro Hardware to as many consumers as possible. So most likely we will see something which falls into the Prosumer category. Good enough, but with enough gotchas to make it fail in the professional world.
But who cares? As long as there are enough fanboys who buy every Apple product, no matter how ridiculous it is, the new Mac Pro successor product will be a stellar success. And even if it fails, who cares about a failure in a tiny segment of Apple's finacial revenue? Apple will declare the pro segment as dead and everybody will be amazed by Apple's insight into the market.
Because how could you be wrong when your're making a sh... load of money?
