The MAIN reason most ppl's computers have crappy battery life is because they leave the computer plugged in after the battery is already charged, I have no idea why it kills the battery but even my parents' brand new 17" powerbook still has that problem. So, if you want long battery life, just friggin' unplug the computer when it's done charging.
I hear so many ppl complain that iTunes doesn't support WMA, I'm sorry, but that's because WMA SUCKS! It's the second worst codec I believe.
