Maybe WanderingKnight really doesn't want to know what contract rates are for computer or network support work.
The downside of course is that your clients usually don't want you around until the fire and smoke makes it hard to see ("we'll save money by not putting oil in the engine, yeah thats it!")
I keep telling them cut-rates for showing up to PREVENT disaster but Noooooo.... (bah
).
GUI vs command-line really shouldn't be an either-or situation for a general purpose OS (rather than a "programmer" OS or an "appliance" OS). You should be able to press the shiny buttons to do task-specific activities and basic configuration -- and then be able to dive under the hood for power work, esoteric configuration (like, say, multiple gateway networks where what protocol or app drives which gateway you use), or other "tinker" stuff.
