Saw this post on slashdot and thought to share it here. Basically it's about some kid distributing Linux discs in his school and his teacher conficated the disc and told him that there is no such thing as Free Software. The teacher went so far as to comment that Windows runs on virtually every computer. Well... in my house currently there are 3 computers, 2 using Vista and 1 using Linux, I would say it's pretty safe that not all computer run on Windows, At least 33% does not :)
