The new Mac Pros will be out soon. And there will be pro displays too, no doubt.
At that point, those who demand extra quality will be able to buy it, at the price it takes to get it.
In the meantime, the consumer-level iMac will continue to fill its niche admirably, for those who want to pay less and have all-in-one convenience.
I'm amazed that those who talk so much about professional image quality are focusing so much on a computer aimed at bedrooms or living rooms, rather than professional studios. In a work environment, one is likelier to see the iMac on the desk of the accountant, salesperson or secretary, rather than the Creative Director.
That such a domestic or office machine is even being considered by imaging pros as an alternative is a testament to the high standards the iMac has attained. But of course, in the current economy, we must not be too critical of those who take the cheap option, desperately hoping to get professional quality from a value-packed consumer device.
