As you get older, the differences just becomes larger and larger. At some point it just gets ridiculous. My current laptop has almost 1 million times more RAM than my first computer (40 GB vs. 64 kB).
It's just impossible to compare the numbers when the differences are that large.
And of course, a post like this is not complete without me noting that the response times when pressing a button on the keyboard was vastly faster on my C64 than my modern machine.
