Laptops all the time?

The more I contiune to think about these laptops we have, more often I get a headache. As a pessimists, my mind goes straight to the bad things of using these laptops. I think that its a bad idea, theres more bad things than good about these computers. Batteries could die, parts could become broken off, and laptops could be left at home. Another larger issue is the internet, the laptops are on the school's wireless internet, while at home, some may not have wireless to use. These laptops can be helpful, the the bads outweigh the goods.
