Buying a Mac Pro to "build iOS apps" or even to do heavy Photoshop work is a waste of money. The people that bought them for those reasons did not make an educated decision. A 15" rMBP or iMac is perfectly fast for those tasks.
The Mac Pro is a reasonably priced dual compute GPU workstation. But it's enormously expensive when compared to what most people actually need.
I'd say that if you are doing 4k Final Cut Pro work or writing your own OpenCL software, this machine is for you. In the future it may be suitable for people using GPU-based 3D renderers (I don't think there's any great ones on OpenCL at the moment).
Aside from the above niche target market, the Mac Pro target market doesn't exist yet. Apple seems to be using this machine to push the development of OpenCL and to push the development of "Pro" software for Mac OS X in the direction they want to see it go.
Personally, I think it's a very exciting direction to take pro software. I hope many developers jump on board. Once that happens I think we'll start to see a larger target market for the machines.
