The concept simply wasn't very good, no amount of explaining it or marketing it would've changed that.
It was a controller with streaming capabilities that only went about 20-30 feet away from the console which was connected a much better quality home HDTV, why would you want to use a shitty 6 inch sub HD display to play games on when it basically had to be in the same room as your HDTV?
Also the whole asymmetric gameplay thing didn't work well for games, people can only focus on one screen at a time, asking them to look up/down and keep track of two screens added nothing to 99% of games and made some of them (Star Fox 0) harder to play for no reason.
