interesting article! I knew that at some point I might have to learn to use the command line to get the most out of my linux, thought I was ready and willing, yet have resisted and failed to do so. Also knew there would be other differences, which I gladly accepted. I just have this thing about "backward compatibility" or being able to keep features that I really like just the way I like them when upgrades come along, being given the choice. That doesn't always work, whether with windows or linux, but that doesn't mean we don't all still try to keep things the same when those particular things work better for our particular situation.
I'm doing aquaponics, and am raising catfish (only 3 survived my early ineptitude), goldfish, and tilapia. It's an awesome learning experience.
