I am from the year 2020, and using my time machine to write this in year 2008.
The meal in a pill is overrated and the implanted supercomputer keeps crashing. I guess it was a bad decision having Microsoft making the OS. Some even turned blue of dead.
The hoverboard, holigraphic movies and jetpack are really cool.
We are still waiting for the personal space ship, infinite energy source, teleporter and hangover cure.
I don't think the hangover cure ever will be discovered...
