Quick--what's the best-selling game system of all time? Nope, it's not the PlayStation or even the GameCube. And it's definitely not Xbox. It's the humble little Game Boy from Nintendo, which, for the record, has sold more than 142 million units since its launch in 1989.
The Game Boy Advance SP ($99.95), due out March 23, should help keep the good times rolling. About half the size of the Game Boy Advance, it sports a backlighted screen, rechargeable lithium-ion battery and a choice of a pretty cobalt blue or handsome platinum case.
The improvements could present a mixed blessing. As any...
