a car has many uses outside of running to the store. a hand scanner has one use.. to maybe save a few minutes. Yep. same thing.<quoted text>
Jay W. when the car was invented: "Why do we need these internal combustion engines? Horses are just fine. Cars won't save us any time from our trips to the grocery store. They take forever to warm up in the cold, but I could just hop on my horse and take off."
I have no problem with innovation and progress, it just needs to be something that is providing a real benefit to society. And saving 5 minutes at the grocery store at the expense of someone losing their job is not a benefit.
