I found it fun to use cassettes, laser discs, CDs, DVDs, mini discs, mp3 players even though I no longer use any of them. Also found it fun to go Atari -> Amiga -> DOS PC -> Windows. And Atari 2600 -> NES -> SNES+Genesis -> PS1 etc..
I agree it sucks when support ends but I enjoy it checking it out while it exists.
