Android/Windows: ClipSync is a simple application that works in the background to keep your Android and Windows clipboards in sync.
To get set up, just connect your devices to the same local network, install the Windows client application (OS X and Linux versions are in the works), and connect to it with the free Android app. After that, everything should work automatically in the background, with no need to open the apps repeatedly.
Copy an address from a text message on your phone, and it'll appear on your Windows clipboard. Copy a long text snippet on Windows, and you can paste it into any Android app. ClipSync even pairs the clipboards of multiple Android devices on the same network, which is perfect if you have both a phone and tablet.
