Battery Life: How Long Does a Battery Need to Last?
 

When the first portable cell phones emerged, they needed a battery as big as a suitcase if you wanted more than half an hour of conversation time. Fortunately technology evolved and this isn’t the case anymore (my cheapo Samsung cell phone can last as long as five days between recharges). And hopefully laptop computers are going in the same direction

I don't understand why people are complaining about things when they are the cause of the problem :rolleyes: . He shouldn't be surprised that he can't watch 2 movies when he chooses blu-ray and doesn't want a big laptop with a 9 cell battery... It's like racing with a jeep against a F1-car, every device is made for a specific task.
