If the short-lived battery built into the PS Vita is a hang-up for you, Sony Worldwide Studios boss Shuhei Yoshida shared some news with IGN which will either reassure you, or redouble your rage. "If you have not noticed we just announced the peripherals for PS Vita, as well," Yoshida said, "and one of the peripherals is the external batteries. So if you're flying from New York to San Francisco, or vice versa, you have no concerns if you have an additional external battery."
The only thing to be concerned about, it seems, is the cost of such a peripheral. If it follows the price model of the Vita's memory cards, it could be cause for concern, indeed.
