The original N-Gage made a few astoundingly bad industrial design decisions that came up in literally every review. * They put the phone microphone and speaker on the side of the device, which meant holding the top of the gadget to your head if you wanted to use it as a phone without a headset -- this was both awkward physically and looked phenomenally stupid. * You had to remove the battery to get to the game cartridge slot! Again, really awkward. Really, the ergonomics overall were kind of baffling. * It had a portrait orientation screen that was slightly lower resolution than the Game Boy's, which made doing ports of games designed for the landscape orientation more common everywhere else more difficult. The updated "QD" version fixed a lot of the weirdness, and it's possible that if it had been the original N-Gage, things might have gone a lot differently. Of course, that's kind of a theme in the Nokia story in the mid-to-late 2000s, I think -- they got really good at shipping terrific products just a couple years later than they should have. If Symbian^3 and the N8 had come out in 2008 instead of 2010, Nokia's fate might have been pretty different. (Emphasis on "might," to be sure.)
