Reviews are starting to come in on the Apple Watch, but the overall consensus is what might have been predicted: that it is, by far, the best smartwatch in the world; that it redefines the bar for smartwatches in the same way that the iPhone did for mobile smartphones in 2007; that it makes nearly all other smartwatches look like toys. However -- much like the initial iPad reviews -- there is a lingering question of how much need there is for it.
