My 48K Speccie's still in the loft. I'll never forget the kids spending ages loading a game from cassette tape, then immediately deciding they wanted something different.
And my (now) wife playing Wriggler for hours and days, and never getting quite to the end.
Also puts me in mind of arguably the best Spectrum emulator, Warajevo, which was written in wartime Sarajevo between bombing raids and power cuts. Quite an achievement.
