OK, let's get to the basics: Can you cook a meal? Can you cook more than one type of meal? Can you sow and mend clothes? Can you run a family household on, say, £90,-- a week? Believe it or not, there are ordinary people who can (some can even look after a baby!); there are computer geeks who can't. I'd say they are pretty essential life skills myself. And as a PC user, I consider DOS pretty essential too (never know when Windows goes down on you and there's just you and an emergency boot disk) but that's just me. No offence dude, but if you don't know DOS you have no right to call an Apple user an idiot. There are Apple users who have never had the need to learn how to swap or format a HDD, or expand the memory. They think that if they have reason to, they will --else they'll get the Apple shop to do it. Again, nothing wrong with that.
