No matter how convenient, and sometimes absolutely indispensable, it is to be able to take your work around with you travel, at times you can't help but wish that they'd think of making those laptops a little lighter to carry around.

Well, the good news is that they've already thought of that and done something about it too. Today, laptops come is weights as light as two pounds, which makes them an absolute pleasure to carry around.

Lightweight laptops can be broadly classified into three.

Generally a preferred choice among lightweight laptops, the thin-and-light laptops offer powerful mobile processors, are approximately 1 inch in thickness and weigh almost 4 to 6 pounds. The display is usually a widescreen of 12 to 14 inches. They come with a 40 to 80 GB hard drive, an optical drive, networking features like LAN, modem, WiFi and an optional Bluetooth. Popular models among others are the Sharp M4000 and the Toshiba Satellite M55-S325.

The Ultraportables are a good choice for people who need to get their work done between frequent travel. They weigh less than 4 pounds and are less than 1 inch in thickness. With a screen smaller than 12 inches, they also some with a 30-60 GB hard drive, networking options, a touch pad and a small keyboard. Popular models among others are the SONY VAIO VGN-SXP and the IBM ThinkPad T41.

A lot similar in size and weight, to the ultraportable counterpart is the Tablet PC. You can make hand-written notes and navigate using a stylus on its screen. Amazingly small weights, as low as 2 pounds, make this a popular choice among laptop consumers.
