Microsoft Windows remains the dominant desktop operating system with approximately 90% of the client operating system market. If Microsoft's monopoly is ever going to be challenged by Linux, there has to be an easy way for Windows' users to be able to learn about this rival operating system. However, it would be naive to think that a Windows user is going to wipe their Windows partition, write off their years of Windows computing knowledge and install Linux just to see if it has more to offer.

Messenger, Windows Live Messenger (formerly called MSN Messenger), and the venerable Internet Relay Chat (IRC). The IM clients featured in this article either cater for as many different networks as possible, or focus on a small subset.

The vast majority of Linux users would never be satisfied without access to a graphical user interface. However, even in 2009 there remain many reasons why console based applications can be extremely desirable. Although console applications are very useful for updating, configuring, and repairing a system, their benefits are not only confined to system administration. Console based applications are light on system resources (very useful on low spec machines), can be faster and more efficient than their graphical counterparts, they do not stop working when X needs to be restarted, and are great for scripting purposes. So what can users do with the command-line? There is a wide range of console based software which performs the same or similar functions to their graphical equivalents, even in the field of multimedia.

Online shopping is the activity that consumers engage in when purchasing products or services over the internet. This activity has many distinct advantages over 'traditional shopping' for both consumers and the businesses.

Mainstream Linux distributions typically default to one of two desktop environments, KDE or GNOME. Both of these environments provide users with an intuitive and attractive desktop, as well as offering a large raft of multimedia software, games, administration programs, network tools, educational applications, utilities, artwork, web development tools and more. However, these two desktops focus more on providing users with a modern computing environment with all the bells and whistles featured in Windows Vista, rather than minimising the amount of system resources they need.

This article focuses on software which emulates home computers, a class of personal computer which reached the market in the late 1970s, and became immensely popular in the following decade, selling many millions of units. Leading home computer companies included Commodore, Sinclair, Atari, Apple, Acorn, Tandy Radio Shack, and Amstrad. Many of the earlier machines (in particular the ZX Spectrum and Commodore 64) often ended up being very game oriented. However, the later home computers had more sophisticated hardware which widened their use in other areas. For example, the Atari ST was used professionally in music studios, in desktop publishing, and had a wide selection of office software available. However to many users it was still regarded as a games machine.

Emulation refers to the duplication of functions of one system using a different system. Specifically, an emulator is software specifically written to emulate aspects of the original console or computer, primarily the CPU, I/O and memory system.
