#5 Nokia N-Gage QD
Yes, the N-Gage platform, no matter how you played it, sucked hosewater. You have to admit, however, that the QD fixed just about every single one of the original's faults. Side talking? Gone. Extremely annoying game card switching? Gone. MP3 playback? Go... Okay, maybe that last one wasn't bad, but listening to music on an N-Gage was about as lame as playing a game on it or using it to make calls.
