To get decent frame rates, the application has to render something in the same format as the physical screen before blitting it to a window.
The same thing applies when accessing video ram directly, except there is no overhead for blitting etc.

So basically - I still don't get why applications shouldn't have access to the framebuffer, because it's really needed for games, emulators etc.
