I so much agree. The price difference to all its predecessors is killing the otherwise brilliant new machine. I actually had set aside about 5 to 6k for a Mac Pro with a screen, but no luck for me. I am currently using a 27" iMac, but I would like to have a desktop class graphics card and the 27" screen is a bit small compared to the 30" available before. My only hope is, that on the footsteps of the Mac Pro, there will be other updates to the Mac line upcoming. And if Apple is actually listening: stop screwing users up with memory and storage pricing. A healthy premium I would happily pay, but not several x factors vs. market prices. At least give users reasonable upgrade abilities.

Having an iMac on my desk also makes it difficult just to add a PC to my setup, as I would need a screen on top of this (and my desk space is scarce), but one day I might do the step - recent Gnome desktops have become very nice, and with Wayland the Linux display stack is getting nicer too.
