I just got one too. First page with data such as time, speed, heart rate, cadence, temperature. Another with the heart rate graph, heart rate, zone, average heart rate, and percent of max. The third has speed, gradient, heart rate, cadence, distance. Basically I use the first page for standard information, the second when I'm working hard, and the third when I'm climbing (although I did the Deer Creek Challenge yesterday and used the second page a lot when I was climbing too).

It seems like a pretty cool gadget so far!
