I also recieved an Edge 500 as a gift, and I'm very excited. I am in a similar position as you, in that I anticipate getting a power meter within a year and was looking for a computer that will be accessible. My only gripe, and it is with polar more so than Garmin, is that my HR monitor is not ANT+. womp wah. I am on my way out to look for a cadence/speed sensor so that my time on the trainer is a little more interesting.
