WirePosted writes with an ITWire article about the problems that Apple's AT&T exclusivity deal could pose in the coming years. Initially the company needed AT&T's commitment to the project, to ensure features like visual voicemail would work. With the iPhone a hit even at its current high price that no longer seems to be the case. Can Apple afford to stick to an exclusive carrier in the future? If for no other reason than consumer choice? "iPhones are being sold unlocked in the markets of Asia where you can't get them with a carrier plan, but they're also being bought and unlocked in the US and Europe. The message is that many and probably most iPhone buyers would like to be given a choice of carrier when they buy their iPhone. Some would be prepared to pay more as they do with other smartphones and buy their iPhone unattached to any subsidized carrier contract. The point is many consumers feel no loyalty to carriers and resent being forced to choose one."

Ponca City, We Love You writes "There will be a program on applied physics and real time strategy that you might want to watch on television today. Conservation of momentum during elastic and inelastic collisions is one aspect on which to focus as players tackle their opponents. It is of critical importance that the Patriots bring down New York's huge and powerful running back, 6-foot-4, 265-pound Brandon Jacobs. An average-size NFL defensive back's mass combined with his speed — on average, 4.56 seconds for the 40-yard dash — can produce up to 1600 pounds of tackling force. A tackle with half a ton of force may sound like a crippling blow, but the body can handle twice that amount because the player's equipment spreads out the incoming energy, lessening its severity." Nanotech specialists from Cornell have developed their own take on the "physics" of the Super Bowl by creating the world's smallest trophy, which will be awarded today to a contestant who best explains an aspect of football physics. Just some food for thought while you watch the game on your brand new HD television, though you'd better not be watching it in a church.
