Why doesnt my computer come with a battery charger? Much more!?

Im buying a dell, and im on their website, and i was just about to order my computer, and i realized it doesnt come with a charger! Shouldnt it come with the computer? Also, i have the option to get ( McAfee, Norton, or Trend Micro) for internet security, and there's a big price difference, which one should i get, and one last thing, i can go from 80GB to 120GB for $25 more, is it worth it? BTW it only has 1GB memory

If it is a notebook, or another battery-enabled device, than it should come with an AC charger.

I wouldn't choose any of the protection software products mentioned, but it is more a question of taste. Choose whatever you prefer and whichever is more convinient to use for you. Getting a 120Gb drive would be of more preference to me. When you order a new laptop, you just pay the difference between the drives for the upgrade. But if you decide to upgrade when you've already purchased it, you'll have to buy a new drive for, say, $75 and the old one will be of little use.

1 Gb is enough if you're not running memory intensive tasks and not running Vista. I'd recommend 2gb at least when buying a new laptop.
