How many times did I watch Back to the Future Part II and think... When will I get my hover board? When will flying cars be a reality? Etc, etc. And if you remember, this movie was supposed to take place in the year 2015 (30 years in the future from 1985).
One of those super cool concepts will be coming to life next year. Nike will introduce self-tying "power laces," as worn by Marty McFly in Back to the Future Part II. Pretty neat, now just need to wait for that flying car that runs on items from my recycle bin.
