8 bit sound (Score 2, Interesting)

As a GBA developer I can tell you that the GBA can at best do 8bit 16khz music, perhaps slightly more with a custom hardware assist, far from the 16/44.1khz cd standard. If you regularly listen to music through a fuzzy telephone, you may like the GBA's sound. And don't even think about the original GB. The GP32 is the only handheld game platform at the moment that comes close to cd quality.
