But they both absolutely crushed the quality of almost any keyboard you get on a computer today.
But it was double the price, putting it out of reach for many more families than the Spectrum. This made a kind of critical mass that lead to a huge community around the spectrum in the UK. And a fantastic burst of creativity as the barrier to entry to writing video games dropped as low as it would ever get.
Perhaps the best thing about the Spectrum was that the manual, which documented the built in BASIC programming language and also the Z80 asm opcodes.
Edit: I should probably steer clear of culture war topics but let's be honest - the designers cut every corner they could think of and consequently the Spectrum looked and sounded atrocious compared to the luxurious C64. But I probably do owe my tech career to one.
The Speccy owners tried to prove otherwise during countless arguments in the schoolyard, but deep down they knew.
I used the C64 only for games, and the spectrum for my own programs and the odd top game
and yes I was on both sides in the playground,
but the C64 had something missing that the spectrum had, hard to put a finger on it, the spectrum did have inferior games (based on the specifications), but It was more accessable or hackable (in todays speak)
I'd say the spectrum kids was more into modding it, typing their own code from magazines and learning stuff, but the C64 kids used it more like console. and could not see the reason for having a spectrum (due to the inferior spec etc..)
But all machines of that era were so low level with plenty of tricks to exploit.
maybe it was the school I went to and the information the collection of kids had
The C64 was a great music-synth with the capability to do 1 certain type of game kside scrollers) in 16 shades of brown vut that was it.
The sheer endless variety of games the Speccy supported knocked the C64 into a cocked hat.
Back then, C64 vs Spectrum discussions were like vi vs Emacs. Good old fashioned tribalism is a thing of all ages.
I do find the Speccy charming though!
