Observer_X, I went back to school for my degree not much younger than you. That's when I was introduced to Linux, Mac and got into depth with Microsoft, Home, Professional and Server variants. Server is the only version of a Microsoft product I would ever willingly install. I have 10 on my current laptop, but when I got my previous laptop, 8 honked me off so badly that I wiped the HD and installed Ubuntu at least 3 months before the 6 month warranty was up. I liked Windows 95, 98, 98SE, XP and 7. Current builds of Ubuntu install and operate in a manner that would be highly intuitive to an XP or 7 user. And like Kenrae said, Linux is still free. Places that charge, charge for materials(disks or thumb drives) or support. Still a lot of enthusiasts out there willing to help for free. And there are user groups consisting of misfits like me who like to meet face-to-face over coffee and donuts on occasion. Age range is huge, 18-70+(we used to have some even younger, but with COVID concerns we've had to limit it to adults)
