I imagine most computer users just surf the internet, send emails, social network and other pretty mundane stuff that doesn’t require much.
I totally agree. There are so many non-technical users out there who only need their computers to do a few things. As the designated tech assistant in my extended family, I, for one, can't wait until the iPad catches on and I don't have to help people with the same old problems again -- e.g. upgrading software or the operating system, weeding out useless leech apps that slow down a computer, removing malware, etc.
The fact is that the personal computer is a scary thing for many people because so much can and often does go wrong.
