This sort of thing is hard to believe when you are a bit tech-minded yourself, but its totally true. I was helping someone out the other day who wanted to install Chrome (and remove IE6). He didn't understand the fundamental concept that web applications (e.g. online banking) store data on their servers, and not on his laptop. After installing Chrome, he thought he would need to transfer all the 'apps' from inside IE6 over to Chrome. He'd used computers for the past 20+ years, so wasn't a noob by any measure.
