N-Gage for sure... Just was an awful idea/design!
In terms of console i think it would have to be either the Sega Mega CD or the Dreamcast (really did not enjoy playing on that) :D
PS4 - Killzone:SF and Assasins Creed 4
XBox One: BF4, CoD:Ghosts, Dead Rising 3, Forza 5
Changing channels with my voice: priceless!!!
