Oh, how could i forget!
I have also owned the Sinclair Spectrum + (with real plastic key, not the rubber ones) which was my first and only true love.*sob*
But the Speccy still lives in my PC in the guise of many excellent emulators.
Speccy Never Dies!!
Other system I\'ve never owned but wish I did:
Commodore 64 ( I was at war with the Commodoreans during the 8-bit home computer wars.

)
Amiga - which I considered a significant milestone in the evolution of multimedia PC.
Atari ST - It has built in MIDI!!!
BBC Micro - if only for the clunky and heavy keyboard to whack people on the head.
Coleco Vision - It was the PS2 in it\'s days.
ZX-81 - The world most amazing 1 KB computer!!! Challenge yourself and see what you can do with 1 KB of memory!!
