Job security is right.
I think I prefer IRL tech support to phone, trying to get someone to follow specific instructions about a PC or program can put me right over the edge. especialy the ones who think "they get it" and get all click happy, lost and have to start all over. Nick Burns, the company Computer Guy from SNL comes to mind alot.
That was the name of my first onsite PC repair biz "The Computer Guy", damned near ran me out of the industry
Now I do networks, VOIP, and Help Desk for our local ISD, thank God for Remote Desktop, VNC and Group Policie managment.
