From the article:
Yet, even Microsoft's so-called "clarifications" do little to ease concern that the next Xbox will be plagued by draconian anti-consumer practices. Major Nelson updated his blog saying "while there have been many potential scenarios discussed, today we have only confirmed that we designed Xbox One to enable our customers to trade in and resell games at retail. Beyond that, we have not confirmed any specific scenarios."
Okay, that's fine. But here's the kicker: "Should you choose to play your game at your friend's house, there is no fee to play that game while you are signed in to your profile." By mentioning the f-word there, we can only assume that there will be fees to play games in any other scenario.
A console that blocks used games is rather unprecedented. While rumors surrounded PS4, Sony has gone on record saying that PS4 will play used games, noting that the "general expectation by consumers" is that when they "purchase physical form, they want to use it everywhere."
And that's true. There are many expectations we have of console games. Being able to buy, play, sell, trade, and share used retail games is one of those expectations. We expect that when we bring a game home, that we'll be able to play it with our friends and family--is that something we're no longer allowed to take for granted on Xbox One?

It also makes mention in the article that not only does it come with Kinect but that Kinect will be required for operation... Yeah, no thanks.
