To tell you the truth, that doesn\'t look much better than the GBA graphicswise or feature-wise. The three major differences are the USB port, memory card slot and MP3 player. But, the Game Boy Color could also hook up to cell phones, and the GBA is supposed to hook up to the Internet (probably with another cable next year). Also, the memory card problem on GBA can be cured by... bringing your game to someone else\'s GBA.
For $275 I\'d just expect more. Anyways, Squaresoft will probably develop for it when Wonderswan dies. LOL
