You have to admit: Jeff Bezos is a business visionary. The man has leveraged his strategic acumen to turn (NASDAQ:AMZN) into a massive e-commerce empire. However, he does have a weakness: Bezos is not a "product guy."

According to a recent Bloomberg Businessweek report, the primary reason the Fire Phone took so long to launch was that Bezos became "obsessed" with the Dynamic Perspective feature. Former Amazon director of user experience Lowell Goss said that including it delayed the device for "years," since it required extensive research and testing.

The thing is that "years" in the smartphone market is effectively an eternity, especially in a world dominated by Apple (NASDAQ:AAPL) and Google. Smartphone manufacturers come and go nowadays. Xiaomi is only four years young and has become one of the fastest-growing smartphone OEMs in the world. Once upon a time, HTC was the king of the Android camp, but now it's fighting for its life. Waiting this long for Dynamic Perspective will prove to be a fatal mistake.

When Apple launched iOS 7 with a subtle parallax effect, it didn't take long for some users to develop motion sickness. It got so bad that Apple issued a software update in March to mitigate the effects. Dynamic Perspective appears to be iOS 7's parallax on steroids. It may be premature to call since the Fire Phone doesn't ship until later this month, but it's highly unlikely that this feature will prove to be worth the wait.

The first signs that Amazon was working on a smartphone emerged way back in 2011, when a Street analyst conducting channel checks caught wind of the device. At the time, a Q4 2012 launch was expected. The analyst also figured that Amazon would stick with its strategy of selling the device near cost. Wrong on both counts.

Many have panned Tim Cook for similarly not being a "product guy" like his predecessor. There's a key difference, though: Tim Cook is self-aware enough not to call all the shots with product design. Bezos, on the other hand, does not appear to have this quality. Goss says that Bezos is basically the sole product manager at Amazon. In contrast, Cook delegates product design to the actual designers throughout Apple, while making strategic decisions.

Ideally, Dynamic Perspective proves to be an important differentiating factor that sets the Fire Phone apart from the iPhones and Androids of the world. In reality, it will probably end up as a short-term novelty that was pursued at the cost of long-term strategy.
