Questions

• I've only done Sudoko once. I don't really see the point. My lazy students say they do it. And someone on the plane recently was doing it. But she must have spent two hours on a single one. And I didn't see her write anything other than the numbers in the box. No notes at all about the possible solutions. Maybe that explains why she was so slow. Is that how most people do it?
  
• Why do hotels buy fancy, flat panel (LCD or plasma) TVs and then feed them with either a standard definition signal or an awful, noisy high-def one?
  
• Does Sean get any money for all the quotes that APS News uses from him?
  
• More and more, I'm being upgraded from economy to an SUV rental vehicle. Who buys a Jeep Liberty anyway? I suppose lots of people given my difficulty picking out my car in parking lots. The steering is so loose, that you need to use two hands just to keep the thing going straight on the highway. I suppose this impresses those who test drive it in a parking lot and you can steer with one finger?
  
• Does reading a paper on the computer result in a net benefit to the environment? I had always gone on that assumption, but I've since gained an appreciation for power sucked down by computers. I suppose it depends on how often one refers to the paper, and whether the computer would be running anyway.
  
• I know that Blackberries and the like, have really come down in price, but am I right in assuming that everyone walking around with such a device is paying something like, at the minimum, $30/month for voice and another $30/month for data?
