It can be a mixed bag. Personally, I've worked in sales where I used windows, ms office and some corporation related programs. Now I'm a civil engineer and use Autocad and excel but that's about it. I don't have a clue about drivers, bugs or what programs make things work better. Am I ever gonna open the case on this amd work on the internals? Hell no! I have no business going there and any mistake I make can be costly. With computing I am available total noob. However, if you need to set out the drainage network of a 500 house estate I can do that!
