Nikon D1x / D1h with GPS tagging function. Only found out about this recently, although both cameras are either due for replacement [the D1x], or have already been replaced [D1h replaced by D2h]. Don't think the D2h has this function, but I do think this is very useful in some applications, and also presents another way of showing photos [one can show a 2D map showing spots where shots were taken, very cool]. There are cool japanese i-mode camera phones with GPS that do this too, except their camera resolution will be much smaller, thus limiting their usage to more personal use
