I have (had) two laptops. One was for business and contained encryption software to enable me to link to secure government sites. What it had for anti-virus etc I can only guess at, but I never had an issue in 15 years in the field, sometimes on the other side of the world using an aircard. At home I have a fairly decent laptop with Norton Anti-virus and some other stuff along those lines and once a month, I have to clean up files, download some new software etc. Now I don't know the first thing about a MAC, but it would seem that the software is the key and at the end of the day, I guess I don't "get" what's so different about the operation system in a MAC.
