For someone that doesn't know what google is, and are barely able to click on that Internet Explorer icon - much less use it once it does open, my mother is far from what I'm worried about.
My sister, clicking everything that looks flashy, though... Her, I'm worried about.
Yeah, that's pretty much the current situation anyway with a lot of folks.
Would be interesting to know. Based on anecdotal reports, I would guess that we are now today in a situation in which more people than ever are running an unpatched, Internet-connected computer - I'm hypothesising that XP is by far the most 'un-upgraded' OS we've had since mass adoption of the Internet.
