It's mostly for convenience. Occasionally, I need/want to remember a setting 
or, if I get really desperate, when call my ISP and they want me to look at

to look at it -- it means I have to get up out of my chair, ugh!

Yes, I'm on that road. I pretty much want to stay on it but I want the above 
mentioned convenience too. I'm a demanding, lazy little bastard :-)
