Carmack, who recently revealed that he is turning his talents to Apple's iPhone (the graphics ones, not the rocketry smarts) for a "graphical tour de force", has provided his two cents on just how powerful the personal media device really is.

During an on-stage appearance at QuakeCon 2008, the man who's tinkered with every graphics tech under the sun likened the polygon-pushing capabilities of iPhone to that of Sega's late, great Dreamcast. Taking the comparison to more current game hardware, he stated that iPhone is "more powerful than a Nintendo DS and Sony PSP combined", perhaps even nearing the capabilities of the PS2 and original Xbox. Given his statements, we're even more eager to see the two projects id is developing for the device, a "conventional mobile game" and the aforementioned visual show stopper.
