Why do people always say, "You can write it off", like that means it's free? This is 3-year Depreciation Schedule Equipment, And a section 179 expense on something like this typically gives you around a third of your money back in taxes in the first year, up to the amounts allowed.If your company isn't paying for this or you cannot personally write it off then you are probably not a Pro user and don't need it anyway.
I'd say the people that really need this don't even have to think twice about it...
The minimum configuration is $5K, let's just wait and see what the actual cost of a properly configured one is before we start saying it's a bargain. Will these things last three years? I don't know. Before I can convince anyone to spend $40K plus on a half dozen of these for their studio, they'll want to know.
Businesses that don't "Think Twice" (especially with Apple's track record) and just throw money at the newest things, typically don't stay in business very long. I've watched several effects-houses tank with lots of virtually unused workstations, still in boxes, going at fire sale prices. That might be the best way to try one of these.
I suspect Apple is just trying this out to see how many suckers are willing to pay for the space gray finish. I know they sold a lot of nMPs to clients of mine, those were prominently displayed for about a year, and now they're all MIA., although I know of one that has become a vase.
