  6. 6. Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. More precisely, it means that 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 to make it do what 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. FreeSW

  12. 12. Why FOSS and GNU/Linux??(2) No need to install extra Device drivers Multiple Workspaces Desktop full of eyecandy w/ 3D Compiz Desktop and KWin Most Documented OS No more Blue Screen of Death (BSOD) Both Community Support and Commercial Support available Linux is in embedded devices. Easy to Install and Use Linux now used in Mobiles too(Ex. OpenMoko, Android, Maemo,Bada etc.) GeeXbox - A 19MB OS which is a Home Theater based on Linux No Need to buy Pirated versions, Trials etc. No need to use obsolete tools.
