 This is Dan Berg with The Verge, and we're looking at Android 4.4 KitKat on the new Nexus 5. As you can see, there's been a handful of different design tweaks, including the translucent menu bar, and a little animation when you go in and view the apps. It's a little bit like iOS 7, but not as big of an extreme change as iOS 7 was for Apple. One of the changes is going to be to the dialer, and it operates a lot like the Yellow Pages now, so instead of just having your contacts in there, you can also search for nearby restaurants and different places of interest. It'll show you and allow you to contact directly from the dialer. Also, Google Now is going to be a lot smarter, and it's going to be able to give you information based on your location, as well as shows you might like and different sites you might like, and it'll also direct you directly into the app that you want. So Google has combined Google Hangouts and SMS, so they're now one and the same. So by default, when you get your phone, there is no Messages app. However, if you don't like that, you can always download a third-party application and set that as your default messaging app. But as it stands, you're going to be using Hangouts a lot more on Android KitKat. So overall, there has been a lot of changes under the hood. Essentially, it's going to make the operating system run a lot better on lower-end phones. Google promises updates to the Nexus phone and the Google Play Edition soon.
