I am not missing anything + your not increasing anything, you still lose contact surface area and if you know how to brake then you do not need cross drilled rotors especially for the street.

Fair enough... to each his own. My concern is that you are spreading false information regarding the reasoning behind cross drilling and fire slotting. It is true that you can increase braking power by going with a larger diameter rotor.
But, given the exact same size rotor, you can increase the fade resistance of the brakes (and hence increase the braking power over time) using cross drilled/fire slotted rotors which removes the gases between the pad and rotor to increase the surface area contact. When your brakes start to fade, you are approaching zero surface area contact because the pads cannot contact the rotor surface because of the gas between the pad and rotor. Now, if you remove the gases from that scenario (which cross drilling and fire slotting do), then you will have surface contact with the rotor. It is my contention that some contact > zero contact under extreme braking.
Knowing how to brake has nothing to do with the fade resistance of your braking system. Fade resistance has everything to do with the disapation of the heat and the gases. Granted, most of us won't ever approach that fade point on the street or even drag racing but it doesn't change the theory behind how and why it works.
*Edit* Here is a link which partially explains the slotting. Check out the first paragraph.
