Do you guys use tracking devices like this?

Nikon's GP-1, a GPS tracking device that fits into the company's cameras and writes location data into image files, is starting to go on sale for a price of about $210.

 

 

Nikon announced the GP-1 in August along with the D90 SLR, saying it would arrive in November, but didn't give a price at the time. Now it's on sale: J&R.com lists it for $209.99 and Adorama for $209.95.
