Thanks for taking the time to summarize your experience. I am surprised about the long time to get a GPS lock that you experienced with both cameras. My WB650 will reliably lock within 45 seconds from a completely cold start (i.e. hasn't been turned on for days). The trick seems to be to turn the camera on and set it down somewhere with a wide view of the sky. Resist the temptation to hold the camera while it is locking. Either the proximity to your body or small hand movements (or both) seem to interfere with its ability to get a quick lock.
