Microsoft has made its $99 Xbox official. The 360 with Kinect and a 4GB HD is available in Microsoft stores, and is only sold with a 2-year commitment to Xbox Live at $14.99 a month. Check it out on the official Microsoft site. Print the coupon and stop by a Microsoft store for the cheapest ever Xbox.My question: is this kind of subsidized console going to catch on? We did the math, and the ultimate savings over traditional Xbox ownership is about $39 over two years, but the $15-a-month version of Gold might have some extra content.So what do you think? Is this a good idea or not? Anyone planning on picking one up?
