When you're copying text, it's usually so you can do something with it. Mime-O might be able to save you a few taps with it's clipboard popup. Each time you copy some text, Mime-O offers to drop it into a message, look up a definition, or send it right to your computer clipboard. This app came out a few weeks ago, but it's new to us.
The app consists of a few small buttons at the bottom of your screen.
