Isn't it hard to avoid MS altogether though?
MS has such market penetration that it seems to have Windows everywhere.
I've been using some form of Windows since 3.11 (which I was really glad was my first as it wasn't as far removed from DOS and the command line as its successors). I'm going to ITT right now so even if I was inclined to stop using MS, it wouldn't be an option.
I've been picking up a little here and there about Linux, but it's slow going becuase I'm going to school and working right now. I want to become more proficient with Linux because I believe we are really going to see a surge in Linux marketshare in the next year or two and I want to develop skills to be more prepared for landing a job in this fast-changing and competetive market.
