Just the other day, I found out the Nikon has a dedicated GPS unit that fits into the hotshoe and works with their most recent DSLRs and the price ain't bad.

I would love to have a dedicated Pentax GPS unit, as there's been so many times where I've been out shooting in unfamiliar locations and can't quite remember exactly where I took a shot once I'm ready to edit it.
Even better would be a GPS unit built right into the camera itself. You've already gotten the attention of the rest of the DSLR world with the HDR mode in the K7; why not get even more attention by adding a built-in GPS to future bodies?
