I agree that it's more of an oversimplification than a myth, but 150 calories eaten ~= 150 usable calories. If the Twinkie requires 10 calories to digest and extract the energy from you have a net gain of 140 calories. If the oatmeal requires 50 calories to do the same, you have a net gain of 100 calories. I recently heard a news story on this and there are studies supporting this based on calorimetry of colostomy bags & poop, but I'm too lazy to look them up now.

I'm in almost the same exact situation as you, but I've got a bit more to go in my contract being able to leave Sprint without penalty. I wonder how many of us there are- could we get a petition together or something? I'd really rather get a Pre and stay on Sprint than have to go with an iPhone. Maybe Verizon will be more reasonable when they get the Pre...
