Netbooks

Better than a Blackberry but not much bigger than a paperback, the netbook is a new breed of Wi-Fi-equipped computer

What to look for

• HARDWARE: How is the memory, processing speed and connectivity? Are the keyboard and screen big enough?
• SOFTWARE: Most netbooks offer a choice of Linux or Windows. This also affects the software you get or can install yourself
• BATTERY LIFE: As small and highly portable items, battery capacity and how the computer conserves power are important
• VALUE FOR MONEY: This is a new and competitive market with typical prices between £200 - £300, but some models offer better overall value

ASUS Eee PC 901

The Eee PC started the netbook trend with its innovative 701 model. ASUS's latest addition to the market is the tiny and lightweight (1.14kg) 901, which also boasts an Atom processor. It runs on a user-friendly version of Linux, with numerous built-in applications including Skype, and a high-capacity six-cell battery (you’ll get three to eight hours depending on use). It has an 8.9-inch screen, but its keyboard is a bit small. It's better for brief rather than longer typing sessions. It has an SD memory card slot, three USB ports and the usual wired and wireless networking options.

HP Mini-Note 2133

HP crams most normal laptop features into its 1.44kg Mini-Note. It boasts a 120GB hard disk, 8.9-inch high-res 1280 x 768 screen and near full-size keyboard. It runs Windows Vista or you can buy the less power-draining Linux edition with a lighter three-cell battery. Both versions have the usual hardware specs, such as a webcam, but there are just two USB ports. While it's a decent option, there are drawbacks: the VIA C7-M processor struggles with large documents and memoryheavy applications, and the screen is good for graphics, but text becomes eye-strainingly small.

From £299 to £389 HP

MSI Wind U100

The Wind U100 is as light as an Eee PC 901 and also has the Atom processor, but comes equipped with an 80GB hard disk, 10-inch screen and a superior keyboard. Crucially, these don’t make it too heavy to lug around. It's sold with Windows XP or, for less, with Linux. You can also add Linux yourself alongside XP later. Upgrading the relatively limited three-cell battery is advisable. The Wind has a number of variations including models with an 8.9-inch screen or 120GB hard disk. But whatever options you choose to go for, the Wind is a winner.

From £280 to £375 MSI

Acer Aspire One

The attractive Aspire One has Intel's new Atom processor as its beating heart. You can buy it with Windows XP and an 80-120GB hard disk or an alternative Linux-only system, starting with 8GB of fl ash memory. A three- or six-cell battery pack is available, for less bulk or more working time respectively. The 8.9-inch screen is superbly clear and with a three-cell battery the whole product weighs just under 1kg. Its dual memory card slots and expansion ports (for 3G/HSDPA or WiMax wireless connectivity) make it impressive for the price.
