I know this may sound stupid, but here goes! What are cross drilled rotors good for? Someone told me they cool faster, but for the price difference I know theres another reason...

From what I've heard, the main benefits are better wet traction, longer brake system life, and better stopping performance. Here's an explanation I found on an offroading site that was discussing their applications to 4x4's:

"The cross-drilling, seemingly the stuff of wannabe racer Civics, is worth more than poseur points; it actually helps the brakes work better. Under hard braking, a brake pad's bonding agents burn off and produce gases. Cross-drilled holes allow those gases to vent, helping to prevent brake fade. Also, when water contaminates the rotor's surface, the holes allow moisture and muck out rather than causing the pad to "float" over the surface of the rotor.

"Cross-drilling also improves rotor cooling, again defeating brake fade. On cross-drilled rotors, temperatures can be reduced by as much as 200 degrees during extreme braking when compared to stock rotors. Since braking is essentially the absorption of a moving vehicle's kinetic energy and conversion into heat, rotors that quickly and efficiently dissipate heat perform better. Cross-drilled rotors increase rate of heat dissipation by increasing surface area, allowing gases to escape, and increasing air flow."

Ohh my goodness! Well that just about says it all! Thanks man.. They seem like something I would like to get.. I mean they seem worth the money..
