It happens all the time: You find a company offers a free product, or an open source tool that does exactly what you need. But free often comes with associated costs of one kind or another. During this session, we’ll go over some of the most common types of expenses associated with free (such as time, effort, portability, expertise required, and compatibility). We’ll also take a close look at some popular free programs to evaluate first-hand what they might really cost you and your company.

Notes de l'éditeur
- Not talking about bait-and-switch, not talking about free tshirt with purchase of a car (though I’ve seen lots of iPads that are free with, for example, certain DISH network packages. www.fsf.org Free Software Foundation “think of “free” as in “free speech,” not as in “free beer”. ” –Richard Stallman The free software movement was started in 1983 by computer scientist Richard M. Stallman, when he launched a project called GNU, which stands for “GNU is Not UNIX”, to provide a replacement for the UNIX operating system—a replacement that would respect the freedoms of those using it. Then in 1985, Stallman started the Free Software Foundation, a nonprofit with the mission of advocating and educating on behalf of computer users around the world. A program is free software if the program's users have the four essential freedoms: The freedom to run the program, for any purpose (freedom 0). The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this. The freedom to redistribute copies so you can help your neighbor (freedom 2). The freedom to distribute copies of your modified versions to others (freedom 3). By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.
- Copylefted software is free software whose distribution terms ensure that all copies of all versions carry more or less the same distribution terms
- There are lots of variations between free options Freemium and Demo versions often have limited functionality Know what you need Graphics courtesy Pandora, Spotify, Slacker and iHeartMusic; composite by Mashable/Charlie White
