Its sad to see one of the biggest software companies fail so badly at making a mobile os

I prefer the OS because it has a simplified and easy user-interface in comparison with Android and iOS (again my opinion)

it has great build quality, a good screen, and an awesome OS

The OS is pretty solid

While it's not hard science, controlling for most of the variables shows that Windows Phone is the superior OS in this regard

Some positives; excellent battery life, snappy quick OS, app integration, ease of setup, and overall fun to learn a new dynamic OS.

Not to mention, the best OS on the market as well!

Sucks that windows 10 mobile isn't out , but 8.1 on this phone is really fast and responsive, a little get used to this OS but in a good way such and open device.

- I am a huge fan of the Windows Phone operating system, and it is really nice to see such a powerful, useful and beautiful OS on such a high end phone

The OS is smooth and Cortana is amazing

The consistent and standardized Windows Phone OS makes it very easy to transfer from my Nokia Lumia 920.
