Remember when cell phones were the size of bricks? Now, all mobile phones fit easily into your pocket. In the 80s if you tried to slide a cell into your pocket, you’d have to buy a new pair of pants or hire a good tailor.
Thank goodness cell phones and all technology is shrinking, otherwise you’d have to lug around gigantic versions of today’s micro-stuff. It would be a big pain in the rear and the lower back, probably the shoulders too.
