Will Moto X be a game changer ?

It has been such a huge buzz now since January at least for the Moto X, does the device live up to the expections ?

So far, what has been revealed, hardware wise, it is the same as what is found in the XiaoMi Mi 2A with some minor differences.
Here are the specifications :
- SoC : Dual Core Krait based (most likely S4 Pro) with Adreno 320 GPU
- Display : 4.7" 16M-color 720p (1280 x 720 pixels) capacitive touchscreen RGB AMOLED (the RGB panel was a specific demand of Motorola) display with curved Gorilla Glass with a density around 316 ppi
- Dimensions and weight : 129.3 x 65.3 x 10.4 mm, 130 g. It is a very (like very, very) compact device height and width wise for a 4.7" Display. The thickness is mostly explained by the curve body of the Moto X.
- RAM : 2 GB
- OS : Android 4.2.2 (not 4.3 but we guess it will be available soon, if not, then it should be)
- Storage : 16 or 32 GB
- Cameras : a 10 MP rear Camera with Clear Pixel technology (instead of Bayer's) with a 1.4 µm pixel size (same as the XiaoMi Red Rice/HongMi) and a 2M front camera
- Battery : 2200 mAh which is a bit more than what is found in this range size
- Specialities : Voice Control always on. Extensive customization of the back.

Here are the Voice control and customization promo videos made by Motorola :






It will cost USD 200  for 16 GB version and USD 250 with a two year contract available on the five major us carriers.

Certainly, the voice control feature and the higly customizable back cover are very nice, but, to me, thoses features are not killers one and cannot justify such a high price (most likley around USD 600 without contract).
The XiaoMi Mi 2A while lacking those options is available at USD 299 only in our PhonAsia Store which represents, at least a USD 300 cut.
