Ummm...waste of time? Open your eyes and look around you, more than 90% of the world rely on it, whether you like it or not, its a part of life. Microshaft isn't going anywhere for a while, so you might as well take the time to at least understand it.
Exactly - 90% of the world relies on it - suckers.
If 90% of the world ends up having problems due to windows, I'm just glad I can say I dont know jack about it. I rather flip burgers than waste my time cleaning up after windows disasters.There are just too many windows "knowers" so why compete with them? I have no need of knowing windows, I dont use it myself, we dont use it at work, and everyone I know that does use it seems to struggle with all kinds of problems these days - why should I involve myself in all that crap? :-D
Much better to learn something slightly more sofisticated that can be interresting and fun as well.
