Smart phones like the latest iPhones are the most futuristic devices that I have ever seen in my lifetime. Not many decades ago, they were unimaginable, except on Star Trek. Now, I can’t fathom being without one when I leave the house. They are a supercomputer with an embedded telephone. They are a navigation system, a communications system, a language translater, a private secretary, a portable business office, a portal to the sum of human knowledge. Give all that up? No way!
Oops, my phone just reminded me now that it is lunch time. Gotta go....
They are an electronic version of a Leatherman Tool.
