Unlikely? Sure, but he does make a compelling argument that Apple is planning on dumping something. When you really think about all the issues that Dvorak brings up in his recent column there is certainly change in the air that goes beyond the switch to the x86 architecture.
However, the Mac OS is intrinsic to the Apple brand, and when you question the rabid and devout members of the Mac Cult they will invariably extol the OS first and the hardware second.
Why this is the case continues to boggle my mind as I have crashed more Macs than I can count. Only Apple could base their OS on Unix (one of the most stable systems ever designed) and STILL get it wrong.
To switch to Apple would mean the dissolution of the Apple brand as computer manufacturers and the reduction of their company to solely providers of iPod/iTunes (and new competition is rising now that may even threaten that).
So, given that it is suicide for them to go the Microsoft Windows route, what ARE they going to do? A new OS built upon the Windows model? As Dvorak reminds us in the most recent TWiT cast, “Drivers, drivers, drivers!”
I don’t have an answer for you, but the lack of Adobe binaries for the new Mac Intel systems should certainly raise concerns for Apple’s sycophantic customer base.
Watch out, Apple Slaves! Dvorak may be wrong about the specifics, but change is in the wind for your masters, and you may find yourself forced to accept a new way of computing. Don’t worry though, I’m sure they’ll make whatever transition easier by continuing to overcharge you. :)
