well, the purpose of and OS to the DS is the same that DS is a portable game system, why do u buy nDS insnt to play games to anyware u go?well the OS would just expand that, think.. ur out of home, camping or something like that, u took ur Ds with u, when u left u forgot to write that school work u need to get ready tomorow, the DS/OS would just help u there,or u are making a bus trip, ur sick of playing or u cant play that well on the bus, why not earing some music or something like that.. The purpose os a DS/OS is just to expand your computer to anywere u go, its just the same purpose as a PDA, now u are saying, than i will buy a PDA, and i say there ir a big diference between buying a $300 PDA and buying a $20 DS/OS cartridge. im just looking for anyone that wants to support this idea, if u dont want to, thats why i said "interested people only".
