Query: Say goodbye to computer headaches

I've never lost any files on my computer. I can't remember the last time Tiger crashed on any of my 4 computers. I've never had a virus or spyware. I've never had to reformat my hard drive. No one has ever hacked any of my networked pooters.A lot of this is because of my computer background. But I rarely need to call on that background. Tiger is fast and I don't have to fuss with it unless I'm bored.
