Laptops typically cost more than their larger counterparts. And since they are harder to develop, they tend to be several months behind desktops in speed and power. Naturally, the most powerful computers carry the largest pricetags. In many ways, you can scout for a laptop the same way as a desktop. Find one that fits your needs on processor speed, memory, and hard disk size.
Laptops are small, but some are smaller than others.
The smallest can be carried easily, but you may have to skimp on features. To get high performance, you may need a heavier model that packs in all the extra technology. Manufacturers should list how long a battery should last before it needs recharging. The time ranges from several hours to less than one hour at the extremes. The quality range here is great.
