A very fair question. What with the new data center (Maiden NC) I've been wondering how they planned to populate it. Obviously Google took a different path with DC infrastructure (custom design, custom build). Could it be that Apple is going to follow ? Or will they buy large quantities of Sun or IBM systems. The latter would certainly indicate a sea change (after the AIM disintegration).
Note that nothing I've read so far this morning indicates that OS X Server is being deprecated, only the XServe line. XServe RAID went away a few years back. Is it possible that Apple plans to continue using OS X Server under virtualization (on other branded hardware) ? That would be a really big deal.
