I agree. The most important characteristic of a power meter is that it helps you answer your questions, not raise a new one ("I wonder if that's because my power meter isn't telling me the truth?"). Features are nice, portability is nice, price is nice, the way it looks is nice -- but being able to rely on the data you're getting is key. That's why you get a power meter.
