Let me review some of the arguments that I have encountered against Linux, which, in my humble opinion, manifest some subjective reasoning that is used as an over-generalization.
1. Linux is not ready for simple computer users
From my experience and from my observations of the people who run Linux around me, this is FUD. As I said, I am a simple computer user and both my desktop and netbook have been running Linux for two years. In comparison to my 10+ years as a Windows user, I have found Mandriva Linux liberating, more stable, and definitely more reliable than Windows. So has my wife, who had no problem adapting to to the Penguin OS and begged me to remove Vista from her laptop. My brother, who runs Mepis, shares our opinion. And my mother, who was terrified of computers until she discovered Pardus, also agrees. A student of English, who runs Ubuntu and its new Unity-thing, loves his OS. In general, those people that embraced Linux expecting it to be different from Windows migrated successfully. Who says that to run Linux you have to run avant-garde software that requires compiling the kernel?
