I have coworkers who use Eclipse (for Java). It's a CPU hog; often it locks up entirely, crashes are infrequent but, happen. I've tried it; I know I'm much faster with vim. For me, my time is worth more than putting up with Eclipse.
I use 80 characters per line because if I am at a larger monitor, I can have 2 or 3 split windows side by side. If I'm at a smaller terminal, everything's still readable. I find narrower code is more readable anyway. Most developers I admire write like that. In any case, this is a major flame war topic; if you don't like it, I'm glad that your system works for you.
As far as build systems, I'll take autotools and its learning curve and pain over VS any day. I can fix it when it breaks.
What are you trying to accomplish by saying that my problem is not the tools but that I'm bad at programming? Why is it that because you think you can write decent code in VS, that means that I didn't learn anything new when I switched from it? I know I certainly did; in fact, if I could give myself any advice back when I started any sort of formal programming, it would be: get off VS and Windows immediately! I would be three years ahead of where I am now.
