Look familiar? It should: that's the PlayStation Vita, Sony's up-and-coming challenger to the mobile gaming throne. It's made the rounds a few times before, from E3, to Tokyo Game Show, to San Francisco's Vita Hill Social Club, and it even took an early pass through Engadget's review gauntlet -- courtesy of the Land of the Rising Sun, of course. After a strong start in its homeland (followed by a quick holiday slump), the budding portable hit the books, brushed up on its English and barreled its way back into Engadget's game room, demanding another review. And why not? We're happy to oblige.
