I use it as my bluetooth GPS with MSFT streets and trips 2007 in my laptop.
Use it with my Tmobile MDA and Tom Tom Navigator 5.0 as mobile GPS.

The included car charger works nicely when traveling and since its standard mini USB charger, I can use it with my Tmobile mda and other USB chargeable stuff too.

I set the track recording to 1 second and switch it on only when I take photos. It should work for more than that time continuously on a single battery charge and I don’t run the risk of overwriting previous data if I forget to switch it off.

I use G-Tool to export to gpx and use “wwmx location stamper” to update the pictures exif data. This looks tedious, but I have to copy my pictures from the camera anyway, so its just one additional step if I do it at the same time.

I use picasa and Google earth to view my Geotagged pictures using the “view in google earth” option in picasa. You can export the pictures to a kmz file from Google earth, but Google maps dosen’t support kmz with pictures just yet. Picasaweb should support geotags in a few days and I will be in Geotagging bliss.
