My only objection is the logger is a single-function device. It's a GPS with no way to read the position until you plug into a computer. The 24-hour battery life should get you through several days of hiking if you remember to turn it off when you make camp.
If you set a waypoint when you take pictures, a standard GPS can do the job as well. Then if you need a GPS for navigation, you have one. Name the waypoint with the frame number of the first picture you shoot from the location. Eh...but then there's no automatic merge of pictures with metadata, so it's a question of whether you're willing to enter coordinates manually or can forego the use of a GPS in favor of the display-less logger.
Personally, I'd wait a few more months. There are some new cameras coming out
and at least one currently available
that will incorporate GPS receivers specifically for geotagging.
