jfruh writes "When Sony announced the PS Vita TV yesterday, most observers saw it as competition for the Apple TV and Roku, or maybe the Ouya. But gaming writer Peter Smith views it differently; he thinks that remote play, including the ability to stream games from the upcoming PlayStation 4 console, will be the Vita TV's killer-app. In that sense, it isn't so much a low-cost replacement for casual gamers as an add-on to the high-end PS4. '[W]hen you're in the middle of a game and someone wants to watch TV, you can just grab a Vita and keep on playing. (This is similar to the popular "tablet play" feature of Nintendo's Wii U, without the Wii U's limitation of having to stay in close proximity to the base console.) ... For any Playstation 4 household with more than one TV I think the PS Vita TV will become a 'must-have' accessory; it's almost like getting a second PS4 for $100.'"
