On the new Windows Phone version, Microsoft and HTC added something unique to the equation: Cortana integration. Although all Windows Phone 8.1 devices in the US get Cortana, the HTC One (M8) for Windows goes a step further by adding a feature to the Dot View case. Users simply swipe down on the case when the phone is in standby, and Cortana comes to life.

Cases are always an optional accessory on phones, but the Dot View case for the HTC One M8 for Windows is much more than just protection. The case is interactive, showing owners useful information like the time, current temperature and the current conditions. The case is 'dot view' because of the mesh screen gives users a dot-matrix picture of that info.

The Cortana integration comes with unique animation, including a larger Cortana 'orb' that looks better through the Dot View case. Cortana answers any question thrown at her, and she remains on screen until you open the cover to reveal the detailed results (alternatively, you can just hit the power button to turn Cortana back off).

Overall, it is a neat twist for the HTC One for Windows, and it is certainly a distinctive selling point. Although cases are not for everyone, when you tie in the functionality of the Dot View case, it is very hard to resist. You can also see why double-tap to wake is important to the Dot View case.
