Very well written - certainly made me think about the 'good old days'!
I'd love to go back to 1985 or so and show someone my 64GB microSD card (which lives in my phone) and compare it to their shiny new 64K memory board from a minicomputer of the time
A cool one MILLION times as much memory in a single-user device that fits in my pocket, against a quarter-ton machine that had to support maybe 50 concurrent users ......
The amazing thing is that the people who used the minicomputer back then for the most part did exactly the same kind of jobs that the users of the incredibly powerful office PC's of today do.
Progress? I guess that depends how you look at it :D
