Edit: to be more helpful, I just got a Powertap for the first time, and find it incredibly helpful to be able to relay numbers to perceived efforts and to a lesser extent HR zones. If you're used to judging your rides this way already, the power data will really enrich your both post ride analysis and real time metering of your efforts)
