"You just have to look at the linux/windows flamewars to know that a large proportion of techies are far more bothered about what they know and protecting their niche knowledge than are interested in learning something new and expanding it."
After having spent years wrestling with M$ and the artificial barriers it puts in place in getting things done I moved to linux and have been happy. What do I do with linux? I automate Windows system repairs. DHCP boot, offline virus scanning, registry fixes so the things can boot again, disaster migration to different hardware, WSUS replacement, data recovery, password resets, automated installs.
Yes I could have bought software to do each function, but it was less hassle to write scripts and python code to leverage existing stuff within linux than to perform the same operations with the software I could have bought!
I know way more about the operation of windows than I do linux. Yet I am more proficient at getting things done in linux, and it all boils down to the profit vs productivity in the design.
You wonder why some of us are passionate against windows?
