Computers should be like TV sets, or a toaster, or any other appliance.
Turn them on. Use them. Turn them off.
How often does your ...
* DVD player get a virus?
* Refrigerator get a blue screen of death?
* Your stove controls lock up?
* TV Sound slows to a crawl when there is a lot of action on the screen?
* Stereo stop working because you connect a cassette player?
Get real. The local consumer reporter would carry the story and the company that made the device would be changing their name and leaving the country.
That is why I use Linux. I want a computing appliance. I don't want to think about the websites I visit being infected. I don't want to fret over e-mail I open containing a trojan. I don't want my firewall to get wormy or my SQL to get injected (whatever that is). I don't want to buy extra stuff to make my computer work properly (anti-virus, anti-adware, anti-spyware).
I want it to just work. Every time. No excuses. No exceptions. No headaches.
Just like Linux.
