After noticing how much easier the SP is to see than the old GB, i decided to pop in a game i hadn't played in a while.  I bought F-Zero shortly after it came out, but didn't play it much because trying to use the shoulder buttons that much in a game made my hands cramp up and the game was far too dark.  But i decided to try it out tonight on my SP...  HOLY CRAP!  i can play it now.  the SP's base is larger(deeper) so my fingers aren't all bent weird to hit the shoulder buttons and i can see it!  i have a worm light for my GBA, but it is not even close to the quality of light produced by the SP.  Thank you Nintendo.
