Yesterday I purchased a GBA SP at my local Toys 'R' Us.  I got home and popped in MarioKart: Super Circuit.  The front-lit screen really emphasizes the bright/colorful graphics of the system.  Not only was I more immersed in the game, but I felt it made the game that much better.  Anyone else have this experience?  I was also thinking this could affect ,although minimally, the reviews of certain games.  Thoughts? 
Edit: PS, I know that the sytem is the exact same (except front-lit screen and battery), no enhancements, so please don't yell at my "lack of knowledge."
