I did elicit laughter from very young people who saw me single-finger punching into a flip-top. I do recall when "portable" phones were carried in a suitcase. I'm not sure what order of magnitude change we have now with our phones, but certainly more than 10x. And since I also recall, with distaste, updating some dumb Banyan Vines email map on a daily basis, Gmail seems to me rather brilliantly > 10x.
