We've heard from Sega's president that he thinks the iPhone is almost as powerful as their Dreamcast. That's great to hear, even though the Dreamcast was laid to rest some time ago. However, John Carmack seems to think that the iPhone is more like the PS2 or Xbox in terms of power.

He went on to say that it was "more powerful than a Nintendo DS and Sony PSP combined." If that really is the case, then I really can't wait to see some Wolfenstein or Doom on my iPhone.
