That's a good suggestion, thanks. We're always interested in how people use Songkick and what they'd like to see next.

Hi Highwind. I start with the physical computer because that's what most people think of when you say "computer". If you read through to part five, I make exactly the point you do - the computer is the software (more accurately an implementation of a Universal Turing Machine) not the hardware at all.
