what features and capabilitys dose it have and is it worth buying?

hello??

Seriously all u need to do is write playstation eye in google and u will get all the info. Its a good bit of tech.

thanks i didn't even think of that

dude its a web cam.......u play games on ps3 using the cam like eye create, aqua vita, trials of topoq etc

Its probably just like eye toy or other web cam application.

It would be efficient if you could integrate it in a messenger application and talk to other people via web cam

eww, its like eyetoy
