Since when was Oracle in the desktop PC business?
Since Oracle bought Sun, there is remnants of an argument that Oracle now has deep workstation history. Dormant workstation DNA. Sun (before concentrating on super-sizing hardware) was in the workstation business. If Oracle was a different company that dormant DNA might reawaken and it would "perfect fix" for the workstation Mac Pro to find a home in.
The drug problem is that Larry has no intention whatsoever of waking up that dormant DNA. Oracle bought Sun because :
a. don't have to partner with HP/Dell/etc. to deliver their integrated/"appliance" solutions. ( Exadata , Exalogic , Exalytics , etc. )
b. compete head-to-head with IBM/HP for more holistic "big iron" sales. (i.e., take larger fraction of corporate IT budgets. ) in shops that don't want to buy an integrated solution. Charging 25% per year for software support
and 20% per for hardware support brings in more money than just software support.
c. Deep overlap between Oracle shops and Suns shops, for historical reasons.
d. figured they could milk Java for alot more money than Sun was. (e.g., tap deeper into Smartphone revenue streams. )
One of the first Sun hardware products Oracle nuked with the acquisition was the remnants of the workstation line up Sun still had. The only "desktops" left are the SunRays (really local keyboard/monitor terminals to an OS instance hosted inside a bigger box elsewhere ). Not particularly indicative of a good partner to move a workstation to.
More on topic: If Apple doesn't care about the Mac Pro, there is nothing to suggest they would care enough to give the pro line to another company.
It isn't about "care". It is holding onto the overall Intellectual Property. Is there any hardware product that Apple has "spun off" ( Newton almost escaped but was pulled back in and killed). Claris (now Filemaker) was given a long leash ( wholly own subsidiary ) but never technically spun-off.
If it doesn't work they'll box it and it will be like the scene from Raiders of the Lost Ark where it is stored in some "Warehouse 13"-like facility.
I would hope they license OS X to Dell or something, but I just don't see it ever happening. It violates the holy directive from his Jobsness about licensing OS X, and again, it assumes they care.
It isn't some voodoo religion. If some clone vendor ( Dell) gets into trouble with the product one of the first tricks they are going to pull out of the bag is cut price and cannibalize upper end iMac sales. Why should Apple give another company a tool to suck money out of Apple's pocket?
Likewise if Apple made the clone vendors sign contracts that said their products could not fall below Apple's products (e.g, must always be more than $300 above an iMac) , incur all of the charges of modifying OS X for their box ( OS X would be more expensive on this box) , incur the majority of the increase support costs (but still meet Apple standards for delivery ) , and limit their part selection to Apple's approval ...... I suspect no clone vendor would sign that for the expected number of machines to be sold. (it would be a smaller market than what the current Mac Pro's sell into).
Appealing to clones in some subset of the Mac market has even bigger problems than setting the whole market to clone mode.
