Are questions regarding Sony's Play TV for PS3 considered on topic for gaming? I'm not sure if they meet the criteria for the FAQ point:
- Game-specific hardware and utilities
I am going to say Play TV is off-topic.
The fact that a device is used on a video game console should not automatically make it on topic. From what I can tell, Play TV is about watching TV, not playing games.
Defining a console as game specific hardware is starting to get tricky. Their primary reason for existence is pretty clearly to play video games, but that doesn't make everything they do about gaming.
Instead of saying "it's only used by a gaming console, so it must be on-topic", let's just start by asking "is it about playing video games in any way?" If the answer is no, it's off-topic. If there is a Play TV question about playing games, it's fine.
I would be inclined to allow it because the article you linked says it is an
add-on unit for the PlayStation 3 (PS3) video game console
Since this device apparently only functions when attached to a PS3, which is video game specific hardware, I would consider it to be an accessory to video game hardware and therefore admissible.
