My parents share one computer (and my dad barely uses it, just for looking at second-hand stuff on the web he might be interested in). My dad has his own company, and my mother does the administration on the computer. The new computer they have is quite fast (the older one was slow as hell, because of many viruses which I wasn't allowed to scan :/). I'd rather touch their computer not anymore, since it's my fault when they buy a new computer, while the screen was apparently broken after connecting the new computer. My mother could've asked me what the problem was first. And she uses Google Chrome and IE. Firefox is too different for her, she says.
