Well considering most people use windows there is a bit of fact in what you say, but you misunderstand why people dont often see virii in ubuntu.. erm..well here would come the techy jargon if i could just remember it.. Damn! a virus needs to get root access to actually be able to cause damage but even if it cant that doesnt mean virus's don't appear. Linux was engineered with safety in mind so it does it very well.
