The following key points to consider when you are deciding which laptop to buy.

Size
In general, laptops are classified into three broad categories one, the subcompact or thin and light type, which are very portable, do not weigh much and have the most compact overall dimensions. The next size is the type that is also very portable, but will have a larger screen and keyboard. The size that is one bigger than the previous type is what is called the desktop replacement type. This will have an even larger screen and an almost desktop-size keyboard. It will be more versatile than the smaller systems.

Screen
The size of the screen is also a consideration for the type of laptop best suited for you. Those who prioritize portability over other factors will prefer the smallest screen. Generally the size of laptop screens ranges from 12 to 17. For those working with graphics or video, the bigger the screen, the better the performance. Display with a widescreen format is best for working with spreadsheets, multimedia and of course watching movies.

Processors and memory
It is sensible to invest in a state-of-the art processor even if you are a basic user so that it is good for the coming few years.

A good, value-for money proposition would be the Intel Celeron if your computing needs are basic. The Pentium 4 would handle your needs even better. Intel also has a specialized notebook processor tailor-made for mobile technology, called the Pentium M.

As for RAM, 512MB is a must, considering the sophisticated applications that are available today. A laptop with upgradeable RAM would be good if you anticipate running short of RAM in the future. Buy the maximum RAM capacity that you can afford, as the amount of memory that a laptop can handle is limited.

Hard Drives and Optical Drives
The drive size depends mostly on how much you plan to use it. Today, an 80 GB hard drive with a 5400 RPM speed would be optimum, if you can afford it.

As far as removable storage goes, optical drives are the choice today. CD-RW/DVD combo drives are available economically. They are ideal for data storage as back-up.

Networking
Intel Centrino Mobile Technology, combines mobile processing power with built-in wireless networking capabilities. Computers that are equipped with this technology can easily connect to wireless networking areas in the house or office and an increasing number of locations all over the world. This technology also saves battery thus prolonging battery life.
