The good: Inexpensive system with 4GB of RAM and 64-bit OS.

The bad: Missing the media controls and HDMI port from previous versions; middling battery life.

The bottom line: This retail version of Dell's basic Inspiron 15-inch, the I15-157B, is a textbook mainstream budget computer, but lacks some of the extras you'll find in other comparably priced laptops.

Editors' note: This review is part of our Winter 2009 Retail Roundup, covering specific configurations of popular laptops that can be found in retail stores.

Dell's middle-of-the-road 15-inch Inspiron laptops have long been an excellent go-to choice for basic computing, especially if you take the time to configure a system to your needs via Dell's online configurator. Fixed configuration versions available in retail stores have been more hit-or-miss, sometimes undercutting the price of built-to-order versions, but also missing some key features.

The $649 Dell Inspiron I15-157B gives you a powerful combo of Intel Core 2 Duo CPU and 4GB of RAM for not too much more than a decently configured Netbook. At the same time, it's about as stripped down as a laptop gets, with no media control buttons or HDMI port (which previous versions had). Adding another $50 bucks gets you a more upscale feel in systems such as the Gateway MD7818u, which has both touch-media controls and a bigger 500GB hard drive.

The Dell Inspiron I15-157B is a model of spartan design, and is never going to be mistaken for a high-end laptop. Its plastic construction and simple, clean lines point to a philosophy of commoditization, acknowledging that in this price range, providing the best value is paramount. The system looks basic, but not cheap. With a glossy black keyboard tray and a matte black lid, we'd almost call it two-tone.

The keyboard is the same full-size model found on Dell's other Inspiron laptops, flexing only slightly under the fingers. The individual letter keys are a bit too tapered for our tastes, but perfectly functional. Missing are the media control buttons we've gotten accustomed to finding on even low-end Dell laptops--a victim of cost-cutting, perhaps. While there's no fingerprint reader, you do still get a built-in 1.3-megapixel Web cam.

The 15.6-inch wide-screen LCD offers a 1,366x768-pixel native resolution, which is standard for budget-minded 16:9 systems. By way of comparison, Dell's online version has a 15.4-inch 4:3 screen, with a 1,280x800 resolution. None of the 15-inch systems in the Budget category of our Winter 2009 Retail Roundup had a higher 1,440x900 resolution.

While you're probably not going to be hooking up a budget machine like this to a big-screen TV via HDMI, we do miss the Bluetooth antenna, which was quickly becoming standard equipment in even the least expensive systems.

Like a vast majority of the system in the Budget section of our Winter 2009 Retail Roundup (covering laptops from $600-$900), the Dell Inspiron I15-157B has Intel's 2.0GHz Core 2 Duo T6400 CPU. Performance among the Intel-based systems was virtually identical, with a slight edge in some tests to Toshiba's Satellite A305-S6916, which had ATI integrated graphics instead of Intel.

Any of these T6400-powered systems are perfectly adequate for basic Web surfing, working on Office documents, and media playback--although running too many applications or opening too many windows at once can lead to some slowdown.

The Inspiron I15-157B ran for 2 hours and 40 minutes on our video playback battery drain test, using the included 6-cell battery. We like to see at least 3 hours of battery life from a midsize system. In the same price range, Gateway's MD7818u passed the 4-hour mark, but also had a bigger-capacity battery (71Wh vs. 56Wh).

Dell includes an industry-standard one-year parts-and-labor warranty with the system, and the Dell Web site has a robust collection of support tools, including online chat, a Flash-based question widget, and 24-7 toll-free telephone support. Retail stores offer a variety of extended warranty plans with your laptop purchase, but they're generally expensive and hard to use, so we do not recommend them.

    Summary: The speaker strip is, in a word: loud. Whereas many budget notebooks' speakers are so weak that we usually leave the volume at or close to its maximum, the Inspiron 15's speaker was so loud we didn't feel the need to crank it past its median setting. ...
