If you've been looking for a good clipboard management tool for Android, there's no better time to take a look at Clipper. The app just updated to v2.1, which brings a pretty incredible feature: cross-device syncing. This means you can copy text from one device, and paste it on another. That's just badass.
Of course, there are potential security worries with a feature of this nature – like passwords, for example. Personally, I copy passwords from KeePassDroid quite frequently, and I know Artem uses LastPass to do the same thing. Understandably, this is the type of information that no one wants shared across multiple devices through the cloud.
