Nostalgia -- what programs do you miss?

What are those programs that you used back in the day (or even recently!) that you look back on fondly and think about how they once were-- or worse, programs that seemed to have just up and disappeared?

What made me think of this question, for me, was Opera. It had everything: browsing, RSS, and torrenting all in one browser. However, a lot of sites loved to break in it since it was the least supported and I eventually moved to Firefox (then Chrome, then Firefox...). Looking at the browser now-- and unsure if I'm just picky or its a case of enshittification, or both-- I'm just "meh."
