The Lounge is rated PG. If you're about to post something you wouldn't want your

They've already said you can disable it, so I don't see it as a negative. I don't plan to use it (I can barely leave a voice mail, not interested in talking to may game console - except swearing at it when things aren't going well of course ), so I don't see it as a positive either.
I'd certainly get a cheaper one that didn't include it if it was an option. But it's hard to directly determine how much you're paying for the extra otherwise. I do consider the extra $100 over the PS4 a detractor though.
