btw Stewart, that pic of your kids watching Dr. Who is genius - it totally captures the small differences between today and yesterday, these tiny differences in our lives that we never really notice except in retrospect.
Untill about 1990 my family didn't have a phone or tv, and our tv was an 11" black and white that was tuned by dial like a radio. When I was 18 and went to university laptops were only for the sons of millionaires, I don't think I owned a computer from when I was 18 (I had a BBC Micro before then...) until 20 or so. My first laptop I didn't get until I started my MA, and even then only because I got a good deal from a friend...
Now everywhere everyone has their laptop with them, on the sofa, checking their emails at the same time as watching tv or chatting...
In the future, we'll look back on the days before laptops with wonder, just as today I wonder how anyone ever managed to meet their friends in the pub without a mobile. It used to just be such and such a pub at 9, nowadays it takes about ten phone calls and the pub and time change at least seven times 😉
