An open source operating system that is for more stable than windows. The only time I use windows is to play a few games. I dual boot linix and windows on the same computer. And linux connects DSL about three times faster than windows. Linux plays my TV card without crashing. Linux does not let me change system settings without being logged in as root. While in windows, I accidentally changed the name of a system file and wasn't able to fix it for hours. Windows and Linux both have their pros and cons. Weigh them both and choose for yourself. Don't dis someone if they choose one over the other.
Linux is for those who choose not to use windows
Windows is for those who don't know they have a choice
