Our Laptop Guide clues you in to what you need to know, from finding the type of notebook that fits your lifestyle to all of the latest trends.

To choose the right notebook--one with the right set of features at the right price--you'll need to figure out how you'll want to use your machine. Match your needs to one of these user profiles to get started.

Home users are increasingly turning to notebooks as their primary PCs; they like that laptops can offer similar performance and features to those of a desktop PC and can be easily moved from room to room. Though of course almost any notebook will do for typical home use, there are two types of notebooks most suitable for home users: midsize notebooks, which tend to be budget-friendly, and desktop replacements, which are usually packed with features.

Students and others on a tight budget should look for a laptop that delivers the most bang for the buck. In particular, students need a notebook that is small and light enough to lug back and forth across campus but rugged enough to withstand bouncing around in a backpack.

If you spend a lot of time on the road, size and weight are the two most critical factors in choosing a new notebook--even if it means sacrificing a little on performance and features. The smallest and lightest notebooks, ultraportables, weigh less than four pounds and are no thicker than a spiral-bound notebook.

If you rely on the same notebook at work, at home, and on the road, you need a well-balanced system. And it has to deliver the performance to keep up with a wide range of applications. A thin-and-light is just the ticket.

If you demand more from a notebook, you'll need a true desktop replacement. Whether you're designing a Web site, editing home movies, or mowing down aliens, your notebook will demand a powerful processor, plenty of memory, great graphics, and a healthy hard drive.
