"""Most people do not have the skill or knowledge to do it themselves."""
Actually its most Mac users that dont have the skill or knowledge to do it themselves.
Please. That was a gratuitious comment. Are you going to tell me that most windows users know how to get rid of spyware and adware? Are you really saying that? I am really curious to know. Please answer.
What percentage would that be? Or do you have exact numbers?
By the way, "its" requires an apostrophe when used as a conjunction of "it is".
I think you would find that lots of Mac users are very Windows savvy... they have to use them at work. They choose to use Macs at home.
Re-installing OS X, if it ever should be necessary, is a twenty minute task. Add another 30 for downloading and installing the update to the latest version.
I'd say that the most pertinent point to the discussion is that most Mac users wouldn't have to worry about it, because spyware and viruses are not a problem in the Mac (or Linux for that matter) world.
A problem on my Macs that I cannot handle quite simply is VERY rare. The one issue I have had any problem with at all was a hard drive that died....and the OS had absolutely nothing to do with it (although the recovery of a bit of important data was probably made slightly easier by the OS).
I could certainly learn how to do it if I needed to, but I don't want to waste one minute dealing with that garbage.
You Windows guys can keep all of your worms, viruses, spyware and kiddie porn to yourselves. We don't want it in the Mac community.
Mac users are people who just want to be able to sit down at the computer and actually start using it. Windows users have to invest a lot of time in security and maintenance to make that happen, while Linux fans seldom actually get to use the computer at all - as soon as they get enough device drivers downloaded off obscure Russian hacker sites to make their system bootable, they're off chasing the next distro de jour.
However, the average Mac user needs to know how to reinstall the OS about as much as Clark Kent needs to know how to treat a paper cut on his own right hand.
