N-Gage



The N-Gage was a rather interesting hybrid: it was a cell phone, but its games came in cartridges like a regular handheld. This was tremendously inconvenient, you had to open the back lid and remove its battery to change games. The controls were clunky, and the screen was tiny. A second model was quickly introduced and fixed many of its issues, but it was not enough to fix its reputation. While it is often mentioned in lists of "worst consoles", it was quite ahead of its time (remember, it was long before smartphones were mainstream), and its fans swear that some of its games were actually pretty good.
