A phone like an iPhone or any smart phone can use any number of apps to make internet calls for free or small charges anyplace you find Wi-Fi. I have several apps on my phone and use them a good deal, most come up with your phones contact list and look and feel like you are making a Cell call. There are so many uses for a smart phone beside Cell calling and GPS. Language translation. Money exchange rates just having something that takes your location and finds what is around you of interest. The internal cameras are really pretty good now and when you get internet sharing photos getting emails and of course posting to Bike Forums. Regardless of if I used it as my GPS device I would still want it along.
