And what about Skype? The notion of a usable video-phone was pure fantasy for years prior to them.
And now, Tesla is doing this again.
I can walk into my grocery store, use their smart-phone app to get discounts on things I want to buy and then wave my phone at the self-checkout station to pay for it all. What a nice future.
Reminds me of these commercials: http://ThisWillTake.Me/youtube/ATT_You_Will . They seem so quaint now.
