I am still trying to figure out if I should get an SP. I usually only play my GBA when i travel. Which is usually every other week. 2 hours each way. The trip there is uasually daylight, so no problem, the trip home is usually at least half during the night. So I would say 1/4 of my possible play time is when its dark. But I also have to figure in that I could be driving during that tiem sometimes, or I may just not want to play. So I really don't think its worth it for me, but then again the time I want to play and can't since I only have a standard GBA, I will be upset. From what I understood its just a light behind the screen right, not true backlight, right? If so how does it compare to one fo those lights that shine on the front of the screen?
