Manufacturing smartphones is a competitive game. I'm talking playing StarCraft in South Korea rough. Succeeding in this market is akin to getting into an Ivy League university, then going on to join the NFL. It's not impossible, but neither is becoming president. If you can't handle the heat, get out of the kitchen. It must be too hot for NEC, as they're bowing out of the smartphone market. Given that this was one of their latest models, the news doesn't come as too much of a surprise.
Garmin CFO Kevin Rauckman stated on the 9th that Garmin may be leaving the mobile phone part of its business on the side of the highway. Garmin has released exactly one Android phone that was met with limited success, to put it nicely. They released the Garminphone with an outdated version of Android and put it on the 4th largest (out of 4) wireless carrier in the US (T-Mobile). The cards were definitely not stacked in their favor.
