HTC Windows 8X

The 8X also inherits its operating system's edgy interface, NFC sharing, and built-in integration with Microsoft Office 2013. Yet the Windows Phone 8X isn't without its flaws. The camera isn't quite as consistently good as other top smartphone shooters (it isn't as good as the Nokia Lumia 920, for one.) 

Missing or underdeveloped apps in Microsoft's mobile OS may also turn some people off. When it comes to such a tight battle between top phones -- be they Windows, Android, or iOS -- small details like those could make the difference between getting bought and getting shelved. If you're choosing between the 8X and the Lumia 920, the 8X is the smaller, lighter phone of the two, and the one that's available on more carriers: AT&T, T-Mobile, and Verizon. It starts at $199.
