Or the Garmin Edge 305. Compared to the forerunner 305, the edge is a bike computer. The implication being it has a bigger display which can display more data fields - the drawback being it cannot be worn like a wristwatch if you chose to go running etc.
There would be other differences too in terms of how each unit calculates the calories consumed etc.
