Since we mentioned that the C64 got middle age (or however you see 40 as) one might also note that the European rival the ZX Spectrum also just turned to (on the 23rd of April). While it might not have been big in America it was fairly popular over in Europe, and certainly then in the UK. More of a rival over here then all this talk about the Apple II etc.
