Third redesign in a row with no updates in between? Great job, Apple.
I really don't know where their heads are at with the Macs these days. Why can't they make a modular desktop with internal expansion capabilities (drive bays, PCI slots, and memory) and a CHOICE OF GRAPHICS CARD VENDOR that doesn't cost an arm and a leg? Seriously, $6k for a nearly empty chassis??
The Mac Pro used to be a be-all-do-all machine. An enthusiast could get one for an attainable amount ($2500 to $3k for a mid-range, anyone?) and know they could upgrade a component in a couple years to keep it relevant, while a pro (or a rich person) could configure one out the wazoo and have the fastest computer in their county for the next six months. Further, they could be configured for any use case -- gaming, music production, video production, 3D rendering, high performance CPU, or any combo of those. Now, unless you are a video pro, forget it, there are much more cost-effective options on the PC side.
And the iMac (pro or regular)? Not an option. 1/3 of the cost of those machines is the expensive screen that is going to get thrown away in three years because the other components are obsolete.
So frustrating. This is why I haven't updated since my cMP 4,1 (flashed and CPU upgraded).
