This is the first laptop I have ever had whose battery was good for more than 45 minutes. It says it's good for three or four hours, and seems to be. I know I have mjg59 and arjan to thank for this, among others.
I'm getting increasingly testy toward people who think they know all about radiation exposure, and how many millisieverts they can absorb without worrying. (I'm talking to you, Ryan.) It's not about radiation you can measure with your handy geiger counter or dosimeter. It's about radionuclides, isotopes of common elements that get incorporated into your body, in your lungs or bones or thyroid, and then sit there irradiating one spot day in and day out. An invisibly microscopic speck of plutonium in your lung exposes you to a tiny, tiny dose of radiation -- practically negligible, by Federal standards, but the alveolus where it lodges is where the cancer will start, ten years on.
One of my daughter's chickens was eaten by a "ring-tailed cat", a native Californian predator not closely related to Felis cattus. I had never heard of them, but '49ers were known to have kept them as pets.
