People in the broadcasting/movie industries, in the digital content creation industry, in the server/media industries. People who are retouchers, graphic designers, animators etc. who want the stability and strength of a Mac platform. Macs are one of the few platforms for example, that can output and process very large images with Photoshop without running out of memory or crashing. Wonder why professional photographers always likes to use Macs? Its because Windows is just not really good enough for all this (despite all that has been said).
Also a Mac Pro is needed because iMacs and Mac Minis DO NOT do the job of retouching properly. I know because I have both. For small jobs yes, for bigger and time-intensive jobs no. iMacs don't support powerful PCIe RAID cards/systems like Areca and the mobile 'M' chips of the current Mac Minis for example, are simply not powerful enough to process big jobs. The same goes for the MacBook Pro - we can't always be retouching on a MBP screen, or have it attached to a dock. Professionals who work with large images on a daily basis need a system that is fast, stable, upgradeable and can use a dedicated and accurate colour calibrated screen.
That's why the Mac Pro is needed.....but it's seriously lagging behind now, it really needs updating. Hopefully the new range will come out with Thunderbolt....
