2001-2005. My computer lab in the school of math and natural sciences (including computer science), had windows 2000 (best windows of all time), Apple Power PCs, and all dual booted linux. All we used for comp sci was linux. Yellowdog on the Power PCs. Learned to program/develop in C++ and Java, mostly used e-macs, goal was to never lift hands from the keyboard or use the mouse, keeps you in the zone. Used Gnome as the desk top environment back then.
So pretty good :)
Today I use linux mint with cinamon for day to day computing, been using it for about 10 years now without issue.
I went back to college for a professional program, and used linux mint in 2022, it worked out just fine. As far as office software, I used word 365 online through the university web portal.
I think word sucks a lot and 2003 and 2007 are the best versions and little improvement since then (improvement is efficiency and easy of creating an end-product), but I’m not willing to re-learn how to master Libre Office, I just can’t be bothered. So no input on that.
