Sony’s PlayStation Vita, which launched this past weekend in Japan, represents the company’s second entry into the volatile handheld gaming market. The original PlayStation Portable found reasonable success as a largely traditional system, with console-style games being bought in boxes from stores just like other PlayStations, but the portable gaming market has changed in the six years since that console launched. With $0.99 smartphone apps like Angry Birds satiating the boredom of many commutes, just how much appetite there is for a "full" on-the-go gaming experience is debatable. Sony's answer? Pack as much as it can into a single device, and price it starting at ¥25,000 (or $249.99 when it launches stateside in February).
