The Bottom Line: The Sony Vaio VGN-NW240F is a well designed mainstream notebook with respectable performance and features for the money.

Specs: Intel Core 2 Duo (2.2 GHz), 4 GB DDR II SDRAM, 320 GB, Microsoft Windows 7 Home Premium, 6.0 lbs, 15.5 in TFT active matrix

The Bottom Line: The Sony Vaio VGN-NW240F is a well designed mainstream notebook with respectable performance and features for the money.

Specs: Intel Core 2 Duo (2.2 GHz), 4 GB DDR II SDRAM, 320 GB, Microsoft Windows 7 Home Premium, 6.0 lbs, 15.5 in TFT active matrix

The Bottom Line: HP's new Envy 15 packs high-powered components into a svelte 15-inch body. The result is an upscale status symbol that still shows a few first-generation rough edges.

Specs: Intel Core i7 (1.6 GHz), 6 GB DDR3 SDRAM, 500 GB, Microsoft Windows 7 Home Premium, 5.1 lbs, 15.6 in TFT active matrix, EPA Energy Star

The Bottom Line: Despite its good looks and a few useful new features, Apple's new iMac is all about business. You can find a larger screen for less, not to mention all kinds of digital entertainment features, but no other all-in-one at this price can boast similar performance. If you need a modestly priced all-in-one for getting work done, we'd recommend no other system.

Specs: Intel Core 2 Duo (3.06 GHz), 4 GB DDR3 SDRAM, 500 GB Standard, NVIDIA GeForce 9400M, EPA Energy Star, Apple MacOS X 10.6, Personal computer

The Bottom Line: As a general purpose productivity machine, the Toshiba Satellite E105-S1802 strikes a number of right notes. Its dreadful speakers, however, limit its entertainment value

Specs: Intel Core 2 Duo (2.13 GHz), 4 GB DDR II SDRAM, 500 GB, Microsoft Windows 7 Home Premium, 14.1 in TFT active matrix

The Bottom Line: Alienware's big and bulky 15-inch M15x pulls out most of the stops, thanks to a superpowered CPU.

Specs: Intel Core i7 (1.6 GHz), 3 GB DDR3 SDRAM, 250 GB, Microsoft Windows 7 Home Premium, 64bit, English, 15.6

The Bottom Line: A large-screen laptop with very good performance, the Gateway NV7802u is an attractive choice for home or office.

Specs: Intel Core 2 Duo (2.2 GHz), 4 GB DDR3 SDRAM, 500 GB, Microsoft Windows 7 Home Premium 64-bit Edition, 7.3 lbs, 17.3 in TFT active matrix

The Bottom Line: Earlier this year Sony was the unquestioned king of all-in-ones designed for home entertainment. The new Vaio L117FX retains and improves on many of the features we liked about older models, but revamped all-in-ones from its competition make the new Vaio seem a touch overpriced.

Specs: Intel Core 2 Quad Q8400S (2.66 GHz), 6 GB DDR2 SDRAM, 1 TB Standard, NVIDIA GeForce GT 240M, Microsoft Windows 7 Home Premium 64-bit Edition, Media center

The Bottom Line: The HP Pavilion Slimline s5220y provides adequate performance for light-duty media editing and entertainment, but its slim tower case leaves little room for future upgrades, leading us to recommend the older Gateway SX2800-01 that offers more features and better components.

Specs: Intel Pentium E5300 (2.6 GHz), 4 GB DDR2 SDRAM, 640 GB Standard, Intel GMA 3100, Microsoft Windows 7 Home Premium 64-bit Edition, Personal computer

The Bottom Line: The design and portability of the Asus UL50AG make it one of the slickest 15.6-inch DVD-drive-equipped laptops we've seen, but an ultralow-voltage processor compromises its computing power.

Specs: Intel Core 2 Duo (1.3 GHz), 4 GB DDR2 SDRAM, 500 GB, Microsoft Windows 7 Home Premium 64-bit Edition, 5.1 lbs, 15.6 in TFT active matrix, EPA Energy Star
