Who uses Linux? The myth from the old days is that it's only for techies and power users. When you needed to put everything together by hand, this was clearly true. But modern distributions make Linux accessible to all. It's no exaggeration to say that you could install Linux on a computer Luddite's PC and have that person use it in preference to Windows.
Up until quite recently, Linux was largely seen as a developers' tool and a server operating system. It was geared toward programmers or was destined for a life running backroom computers, serving data, and making other computer resources available to users.
To this end, Linux continues to run a sizable proportion of the computers that make the Internet work, largely because it provides an ideal platform for the Apache web server, as well as various databases and web-based programming languages. This has lead to the LAMP acronym, which stands for Linux, Apache (a web server), MySQL (a database), and PHP or Perl (two programming languages that can be used in an online environment).
Despite its technical origins, recent years have seen a strong push for Linux on desktop computers. Linux has stepped out of the dark backrooms, with the goal of pushing aside Microsoft Windows and Mac OS in order to dominate the corporate workstation and home user market.
Running Linux on the desktop has always been possible, but the level of knowledge required was often prohibitively high, putting Linux out of the reach of most ordinary users. It's only comparatively recently that the companies behind the distributions of Linux have taken a long, hard look at Windows and attempted to mirror its user-friendly approach. In addition, the configuration software in distributions like SUSE Linux has progressed in leaps and bounds. Now, it's no longer necessary to know arcane commands in order to do something as simple as switch the screen resolution or configure a printer. The situation has also been helped by the development of extremely powerful office software, such as OpenOffice.org and Koffice.
Is Linux for you? There's only one way of finding out, and that's to give it a go. Linux doesn't require much of you except an open mind and the will to learn new ways of doing things. You shouldn't see learning to use Linux as a chore. Instead, you should see it as an adventure—a way of finally getting the most from your PC and not having to worry about things going wrong for reasons outside your control.
Linux puts you in charge of your PC. You're the mechanic of the car as well as its driver, and you'll be expected to get your hands dirty every now and then. Unlike with Windows, Linux doesn't hide any of its settings or stop you from doing things for your own protection; everything is available to tweak. Using Linux requires commitment and the realization that there are probably going to be problems, and they're going to need to be overcome.
However, using Linux should be enjoyable. In his initial newsgroup posting announcing Linux back in 1992, Linus Torvalds said that he was creating Linux "just for fun." This is what it should be for you.
