Actually, yes, 10 years ago the tablet computer did exist. It wasn't a capacitive touch screen available to everyone+dog, but I know I coveted the touch devices that were hitting the computing market more than 10 years ago. There was one in particular that was very promising and ran linux but never got past prototype stages.
Even smartphones were around back in the day. The term smartphone is 14 years old and I remember co-workers with handsprings that could make and receive phone calls over 10 years ago.
I'm not arguing that technology is screaming forward at an unprecedented pace, but it's not nearly as fast as everyone wants us to think. Apple, Samsung and Nokia didn't just spring out of the woodwork 5 years ago with fantastic new phones. They built on the work done by others, many of whom couldn't innovate fast enough to even exist today.
Flying cars on the other hand just seem to have stagnated for the past 40+ years.
