GPS-Enabled Point-and-Shoot Digital Cameras

During the past few months, several new GPS-enabled point-and-shoot digital cameras were announced, including the Panasonic DMC-ZS7, Samsung HZ35W, and Sony HX5V. I am especially interested in the Panasonic Lumix DMC-ZS7. I asked Phil Wherry, a very good friend with considerable expertise in all things technology-related (including digital photography, GPSRs, and geotagging photos), "Which camera looks like the best buy?" Phil reviewed the specifications for the three new cameras and made the following comments:

"All of these look like competent cameras, though there's nothing that stands out as amazing from a photographic perspective. GPS is going to be largely limited to outdoor use, and there's going to be some signal acquisition time. Still, a slow GPS beats no GPS. There's not enough information about any of these cameras yet to make a judgement about which one is best (and "best" is likely to depend on application, anyway). A great deal is going to depend on the performance of the sensors they've chosen, the performance of the GPS chipset, and the user interface that ties it all together. The optics matter too of course. There, the Panasonic probably has the best chance of being decent, since they're using a lens design from Leica (a company that's been in the premium optics business for a very, very long time)."

I would like to hear from early-adopters who can comment, based upon firsthand experience, about the GPS signal acquisition time performance of all three digital cameras, especially the Panasonic Lumix DMC-ZS7.
