Sony and geolocation

It seems like SONY intend to start exploiting GPS technoogy more widely. They have recently announced the GPS-CS1 which looks like it might be a nicer device to use than my trust Garmin Etrex Vista C. The GPS-CS1 looks smaller and lighter - I'm not completely sure what it's dimensions are, some of the information on the SonyStyle webpage is wrong ("Operating Temperature --- 101.6 x 152.4mm (4" x 6")"). The GPS-CS1 ships with (Windows only?) software that does the geotagging.

I've also noticed that there is a GPS add-on for the PSP, although I'm not sure what it's going to be used for yet, other than that there are "GPS-enabled games" available.
