I have a HTC phone that does have GPS built in and can see it being such a money maker for the likes of Google in the future. You can get a version of Google maps for it, which can give an approximate location using the physical location of the nearest cell masts, or if you have a GPS built in (or a blue tooth one) you do get the specific location, tie it in to the satellite view and it does become a useful toy! There is a useful bit of software from a company called navizon which can give you a location either by using GPS or by detecting the wifi hotspots & cell masts the phone can pick up. Currently they pay people using its software for each wifi hotspot/cell mast - I can see them slowly mapping up the location of 95% of all such spots in most majour cities, then sell this data via some form of API to other software makers - imagen a "majour brandname coffee shop locator" running on your phone - the marketing possibilities are endless. Finally one usefull feature of the GPS that I can use now is the ability to add GPS location references to photos taken with the phone.
