4 lbs or less Laptops

The Bottom Line: Nokia's entry in the crowded Netbook field shows that the company's hardware know-how translates to computer design, but a poor choice of CPU should give you pause.

Specs: Intel Atom (1.6 GHz), 1 GB DDR II SDRAM, 120 GB, Microsoft Windows 7 Starter, Microsoft Windows 7 Home Premium, 2.8 lbs, 10.1 in TFT active matrix

The Bottom Line: Sony's bold experiment--a high-end luxury system with essentially Netbook components--makes an enviable coffee shop conversation piece, but one that includes some serious sticker shock.

Specs: Intel Atom (2 GHz), 2 GB DDR2 SDRAM, 128 GB, Microsoft Windows 7 Home Premium, 1.6 lbs, 11.1 in TFT active matrix, EPA Energy Star, RoHS

The Bottom Line: If you're in the market for an affordable thin-and-light, the Asus UL30A-A1 provides great value and a solid Core 2 Duo CULV processor in an attractive package.

Specs: Intel Core 2 Duo (1300 MHz), 4 GB DDR3 SDRAM, 500 GB, Microsoft Windows Vista Home Premium, 3.7 lbs, 13.3 in TFT

The Bottom Line: HP's upscale Envy 13 looks and feels like an expensive status symbol, with performance and features that impress us--but its high price makes it a tough sell over the similar-looking MacBook Pro.

Specs: Intel Core 2 Duo (2.13 GHz), 3072 MB DDR II SDRAM, 250 GB, Microsoft Windows 7 Home Premium, 3.8 lbs, 15.4 in TFT

The Bottom Line: The Viliv S7's small size and Netbook-tablet hybrid design are appealing, but its high price is illogical in a world of inexpensive portables.

Specs: Intel ATOM (1200 MHz), 1 GB DDR II SDRAM, 16 GB, 1.76 lbs

The Bottom Line: A revamped version of Lenovo's slim ThinkPad T400s adds an innovative touch-screen package to the first Windows 7 laptop we've reviewed.

Specs: Intel Core 2 Duo (2.53 GHz), 4096 MB DDR II SDRAM, 128 GB, Microsoft Windows 7 Professional, 3.9 lbs, TFT

The Bottom Line: Samsung brings a different look to a generic Netbook build with the N310, but is there any good reason this costs almost $500?

Specs: Intel Atom (1.6 GHz), 1 GB DDR2 SDRAM, 160 GB, Microsoft Windows XP Home Edition, 2.9 lbs, 10.1 in TFT active matrix, EPEAT Gold, EPEAT gold

The Bottom Line: The 11-inch, AMD-powered Gateway LT3103u does well on price and performance, but drops the ball on battery life when compared with the competition.

Specs: Athlon 64 (1.2 GHz), 2 GB DDR2 SDRAM, 250 GB, Microsoft Windows Vista Home Basic, 3 lbs, 11.6 in TFT active matrix

The Bottom Line: Attempting to create a premium-priced version of a Netbook, Sony has added an HD display to the Vaio W. It's an attractive step-up package, but the internal components are the same as are in cheaper models.

Specs: Intel Atom (1.66 GHz), 1 GB DDR2 SDRAM, 160 GB, Microsoft Windows XP Home Edition, 2.6 lbs, 10.1 in TFT active matrix, EPA Energy Star, RoHS

The Bottom Line: Swelling the ranks of 11.6-inch Netbooks, the Asus Eee PC 1101HA impresses with its design and battery, but having to overclock a slower version of Intel's Atom CPU is a dodgy workaround.

Specs: Intel Atom, 1 GB DDR2 SDRAM, 160 GB, Microsoft Windows XP Home Edition, 3 lbs, 11.6 in TFT active matrix
