Couple of things for me.
One is tiny croutons. I don’t see them anywhere anymore. They taste the same but it’s kind of a pain sometimes to keep the big ones on your fork. The small ones were a little more satisfying to snack on too.
Second is Blue Nehi. Never met anyone else that’s tried or heard of it. Damn it was good though. Big Blue is kinda similar but those always taste under carbonated.
For me it’s Vista. I’ve always felt like I’m the only person who actually unironically liked that thing. It just looked so good, and for my computer at the time at least, it also worked so good (I got a new one specifically for Vista anyway, so I didn’t have the complaints most people had).
7 felt like it improved in some areas (performance on weaker hardware, lack of bloat, better customisability, and so on) while in contrast it was basically nerfed in other areas (more generic design language, worse taskbar by default, too few new features, etc). It took me a short while before it would end up growing on me.
