Nokia N-Gage
Ah, the Nokia N-Gage, what a truly hideous piece of tech bilge you were. So ugly and so functionally useless, it is truly amazing that the N-Gage ever came to market. Part phone, part handheld gaming console, the N-Gage did neither and did neither spectacularly poorly.
What happens if you use buttons designed for a phone on a handheld gaming console? That's right, they act like phone buttons and make gaming a trying experience. Also, what happens if you use a handheld gaming console form factor chassis for your phone? That's right, you end up looking like a berk every time you hold it to your ear.
Nokia thought the N-Gage would be a massive hit, predicting it would ship six million units by the end of 2004 (the N-Gage launched in October 2003). Unfortunately, the device sold under 10,000 units in the first two weeks on sale and, despite lingering on the market until 2005, soon after had a bullet put through its nasty 176 x 208 screen.
