So basically you are advocating people who make their living on their workstations to question their decisions?
I regularly do.
Don't get me wrong: I personally am all for Apple delivering the fastest Mac computers they can possibly make in keeping their Mac Pro line.
But to get to the business standpoint
but from the main business standpoint I dare to say that it is complete business nonsense to pay for a display that you throw away with every upgrade cycle.
I beg to differ; I have in fact, repeatedly advised customers of mine to forego the Mac Pro in favor of an iMac this year. And many of them were people who believed they needed "a Mac Pro, nothing less", kept upgrading their old (Mac Pro) machines instead of purchasing a new faster (i)Mac, etc. etc…
I do believe it to absolutely make sense "from a business standpoint" for many of them.
A Mac Pro just currently just isn't a good value proposition in terms of price/performance for many:
"1000$ more for a Mac Pro won't buy you a faster computer".
A current top-end iMac(3.4GHz i7, SSD) offers about the same performance as a 6-core 3.33 Xeon Mac Pro in most applications*. Yet even with its "27" built-in Cinema Display",
the iMac costs 1000 USD less than the display-less Mac Pro.
* Slightly more in Photoshop, DTP etc…, and only a bit less for heavily multithreaded encoding/rendering.
And you're not going to make the Mac Pro faster with any upgrades - it's CPU stays the same, greater RAM expandability won't matter, save for only the most exotic applications, external HDs can be added externally via Thunderbolt (if admittedly at a higher price due to the casing/controller needed - yet often still less than a Mac Pro with multiple internal drives - and then, the iMac still has the advantage of including a big display).
So why and where's the iMac supposed to be "nonsense", "from a business standpoint"?
