What is an all-purpose laptop? We generally define them as between 14 and 16 inches, weighing more than 4.5 pounds. Some 13-inch laptops that are thicker and heavier than the standard may fit the bill. These are large and powerful enough to serve as your everyday computer, but portable enough to accompany you on the go. By the way, we've tested every laptop in this slideshow in the PCWorld Labs.
