It was a year ago today, that Microsoft unveiled the Xbox One, the successor to the Xbox 360 and the platform on which it’s pinning its hopes in the living room. When it launched on November 22nd of last year, the Xbox One cost $499. For that price users got a single wireless controller, a power adapter, a chat headset and a HDMI cable. Today the cheapest Xbox One is $399 and holiday sales have pushed it even lower. Dozens of bundles have come and gone. So have priorities.
