Dell Laptop under 400

A 15 inch laptop generally is a midsized laptop and midsized PCs are the most popular types of all laptops. They are not too heavy and usually come with all the features that an average user might need. The 15.4-inch laptops everyone lugged around in backbreaking shoulder bags before ultraportable systems became popular.

If you're set on a midsize laptop, one piece of advice we've offered for the past couple of years is to consider a 14-inch system rather than a more common 15-inch one. While you're trading away a little bit of screen size (but not any screen resolution), we've consistently found that 14-inch midsize laptops offer better overall industrial design, specifically because the standard laptop keyboard fits much better in a 14-inch chassis than a 15-inch one, leaving much less dead space on either side. And, by shaving off a little size and weight, these 14-inch models are easier to carry around--which is important, as we've seen many commuters struggling under the weight of oversize laptops.
