She did ask me what I thought and we plan on deciding together what we end up doing. We also have a 4 month old baby and as he gets older and wants to play some games, I'm not sure if the Xbox is as enjoyable for children.
Anyway, we still don't know what we're going to do with it. As of now we haven't opened it, yet.
Oh ok. The OP seemed to me like you were deciding alone, or maybe I was just tired.
That said, sell it, the new generation of consoles is coming (kind of slow) so better put money for that. I understood in a few months something will come out... if only I could remember what. Or you could get the Wii U of course, which is also good since it can do a lot of things.
