My first computer, and something that is often referenced in the UK, or amongst people of the right kind of age.

The Spectrum was insanely popular, though the development of a new machine also coincided with difficult times. (The Sam Coupe.)

Sam Coupe was a technical marvel, pity it had some issues with the first models and it was already at the end of the 8 bit generation.

That's because the ZX Sinclair Spectrum's only claim to fame is the rock bottom cheap pricing: it did not have any revolutionary hardware or operating system like the Amiga. It couldn't do things competition wasn't capable of. The only thing Spectrum competed on was price.
