Mmm, I may have been... slightly more than usually robust. There's nothing wrong with having ideas, as long as you're aware of the prior art, why it failed, and the very limited size of the target market.
It's something that would be fun to lash up as a hobbyist project, even just for local site use. If you want a device, then Pi / Arduino GPS modules are dirt cheap now and you could do initial prototyping using wifi between devices to share their location. 11n claims a maximum of 250m outdoors although reality may have something to say about that.
Once you start factoring in screen, input, sounds, battery and a case though... well, phones exist now, and you'll have to write software either way.
