Here's mine (with powermeter)

Page 1:

Pwr. Zone - Pwr. 3s
Speed - Avg. Pwr.
Distance - Heart Rate
Time - Cadence

Page 2 (Identical, but with Lap values for Distance, Time, and Avg Pwr:

Pwr. Zone - Pwr. 3s
Speed - Lap Pwr.
Lap Dist - Heart Rate
Current Lap - Cadence

Page 3 (Misc. and Ride Stats):

Time of Day - Temp
Avg. Speed - Max. Pwr.
Totl Ascent - Avg HR
Kilojoules - Avg Cadence

Some may think this is a little busy with 8 fields, but the font is plenty big and I know where everything is. I find all the information on my main page and lap page pretty useful except maybe "pwr zone". I really wish they had a power zone field that would use the 3sec average.
