I spent 20-odd years enjoying how how mobile phones went from being huge 2-3 pound 'bricks' all the way down to the Nokia 100 gram 'chocolate bars' of the mid-2000s that fitted beautifully in my shirt pocket.

Then I watched in disbelief as phones began getting more and more swollen every year and got too large to hold comfortably in one hand. (or fit in your top pocket)

Time and again the phone-shop salesmen would look sideways at me when I said I didn't want the latest and greatest offering, but one of the older and smaller phones. My current phone is an iPhone 5S that I have kept for several years.
