Low sales means no sales.
With the significantly dropping sales of Mac Pros, Apple seems to be considering discontinuation of their high-end desktop machines. As per their latest financial call, 74% of all their computer sales are accounted for by their notebooks, with the desktop segment mainly dominated by their iMac line. And given that their iOS devices sell more than their entire computer division, it stands to reason that their least sold product line could well be discontinued.
According to some proven sources, AppleInsider says that the management at Apple has been mulling over the decision to continue supporting the Mac Pro line for as long back as May 2011.
Consider the alternative, that if the Mac Pro line is discontinued, that’s more R&D, customer service & support and advertisement money that can be spent on their more profitable products, or better yet, Apple TV. Regardless of where those unspent resources are diverted, the market in general wouldn’t see much of a disruption in terms of technical prowess. The Macbook Pro lines, and even the iMac support some pretty powerful hardware, and with the implementation of Thunderbolt, existing products can expand usage in many ways. One of the biggest sellign points of the Mac Pro, apart from powerful processors, was PCI Express slots. And with Thunderbolt already able to achieve the bandwidth of PCIe slots, the case for Mac Pros becomes even weaker.
