TeX and LaTeX, however, are still widely used alternatives to word processing and there is an active world-wide TeX community developing a continuous stream of new features and macros. There are some good fundamental reasons why you might want to try out the LaTeX alternative to word processing. First, it's free and it's open source. What's particularly interesting about TeX is that for a bit more work up front, you get a bigger payoff at output time. There are also aesthetic considerations.
Word processors are sloppy.
Few people are taught how to use a word processor correctly, so output generally comes out however it gets slammed in. With LaTeX, the emphasis is on organization rather than on looks. The built-in styles guarantee that your output will look highly professional and follow proper typesetting etiquette. All you have to do is enter the tags and you'll have great, classic-looking output. Not only that, but Linux allows you to have your cake and eat it too.
