That is true! And even after 18 years, there will still be a lot more to learn!It took you years to build up your Windows skills, so the same will be true for Linux. It's a fun process.
Also, I've never been much of a Gnome fan. To each their own, of course. I just don't prefer it.
I agree!I very much enjoy the fact that there's always more to learn - and that the knowledge is freely available to those willing to put the effort in. I'm pretty old, but I figure I'll never run out of stuff to learn before my time is up. That's good. I spent a huge portion of my life in academia and have always valued the pursuit of knowledge.
