It's so obvious this is paid product placement. I heard Microsoft spent $400M on this. Watching the guys in studio yesterday not one of them ever used their surface while on air. It was clearly just a prop. This year Microsoft even created a blue case so the white Microsoft Surface logo would be staring you in the face while JB and the boys on Fox are chatting away.
Of course it's paid product placement. The NFL is a major brand in and of itself that pulls in a massive number of viewers and dozens of other companies want pay to get in on that action. Gatorade, GM, Visa, Riddell, Papa Johns, Bose, Nike, FedEx, Verizon all pay money so they can be directly associated with the NFL (not to mention all the corporate naming of stadiums).
MS is the official sideline technology partner (or some weird title like that) and teams are using the Surface Pro on the sidelines to do things like analyze plays instead of printing off pictures. I'm not surprised part of the deal was to get their tablets into the studios too since there's not many shots during a game where we'll see players/coaches using the Surface's on the sidelines (unlike, say, the new headphone/headset sponsor Bose which gets ample logo time anytime a coach is on screen).
