With the growth in mobile internet usage, the amount of double counting going on is only increasing and so this latest version of Google Analytics is looking to solve this. It is called Universal Analytics and is now in public beta. Check out the launch post here.
It uses a virtual identifier to track individuals across devices instead of dropping individual cookies on each device. It even integrates with your own identifier if you happen to have one. There is a lot of potential to do more with Google Analytics as a result, especially around things like customer journey analysis.
It does require you to update the Google Analytics code on your website though 😉
