"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. For users and developers who want to run an attractive Linux desktop on older hardware, netbooks, or mobile internet devices, neither KDE or GNOME may be a viable option, as they run too slowly on low spec machines (such as less than 256MB RAM and a 1 GHz processor). This article seeks to identify the best lean desktops for Linux, for users that have old or even ancient hardware."
