Looking for an affordable yet powerful smartphone? Consider the Google Nexus 5, which delivers blazing performance with its 2.26-GHz Snapdragon 800 processor and a pure build of Android 4.4 KitKat. Google's latest OS also brings nifty improvements such as voice search with Google Now, easier home-screen switching and improved contact search features. A bright full-HD screen and impressive graphics performance make watching videos and casual gaming an enjoyable experience on the Nexus 5. And for $0 down, it's hard to find a smartphone that beats the Nexus 5 on value, particularly with only $16.67 per month for 24 months.
