I also own a 360 and a PS3, and I gotta say, I think the article is right on the money. The comments by Chaos were pretty thinly disguised fanboisms ("well, I don't see it that way" is usually a dead giveaway).
I mostly use my PS3 for Blu-Ray. XBox Live is easily worth $7/mo for a superior service that does a great job keeping me connected to all of my friends. The fact of the matter is that XBox Live is the reason that multiplayer support on 360 games is the de facto standard, not an optional feature these days.
Anyone who's trying to make the argument that Sony is ahead in online support because they can "purchase/rent things from the PS Store on their PC" is off their rocker. That's a useless fluff feature and you know it.
