Computers: desktop vs. laptop.

Which differences between desktop and laptop computers are real and which are myths based on yesterday's designs? If you can't answer that question, your next computer might be one that doesn't meet your needs or, just as bad, one with unneeded costly extras.

The only way to tell how the two types differ is to compare the latest models head to head. And for the first time in all our reporting on computers, that's exactly what we did. We bought budget-priced desktops and laptops from the leading manufacturers, configured them similarly, put them through much the same tests, and compared features and designs.

We still measured qualities unique to each type, such as the laptops weight and battery life. But even after allowing for such aspects, we were able to rate performance of both types on the same basis. The overall scores in the desktop Ratings on page 43 and laptop Ratings on page 45 are directly comparable.

EVENLY MATCHED HARDWARE

Overall, budget desktops and laptops are nearly equally capable, though laptops cost a couple of hundred dollars more. Both types have comparable, if not identical, hardware, including CD RW and DVD drives, as well as capable graphics processors with enough horsepower for photo editing and gaming.

Price aside, we did find a few differences between the two: Desktops are easier to repair, because they use standard parts that are easily bought and replaced. Because of its modular design, a desktop can still operate without a noncritical component. Laptops are filled with proprietary components that consumers can't service; any failure can put the computer totally out of commission. Given those vulnerabilities, we advise more coverage than the basic warranty provides for any laptop you expect to frequently move from place to place.

Desktops offer better sound than laptops and more options for expansion. You can equip them with surround sound to turn your computer into an entertainment center. Laptops' main advantages are that they're more compact and can be carried and used nearly anywhere.
