My understanding is that they don't have direct access to the graphics hardware working yet.
So the picture is being copied to the framebuffer, a pixel at a time. So things that update the screen often, like a game, eat up CPU time quickly, even though producing the image(NES video emulation) can be done on a 386 with hardly any frames dropped.

The processor(s) is fairly powerful in the iphone and there is something like 128 MB of ram in it. It's effectively a pocket MacOSX system underneath it all.
