Virtual Boy, by about a mile and a half.
I begged my dad for one for Christmas, THANK GOD that my dad thought it was a hideous monstrosity that would spell the end of all productivity as I would be permanently attached at the face to my gaming console. My best friend at the time got one, and after being jealous for all of 3 days, I went to his house, played for a few hours, got my first Migraine, and realized, "You know what, this thing sucks."
My dad's reasoning was off, but damn if the man isnt a hero for saving me from shitty video gaming. We got a Computer instead, it had 3D Movie Maker, and was a MUCH better investment.
