Puzzled.
First off, let me admit I am a TomTom user on other devices, and I really like their software and would recommend it to those with a phone without an option. But, the iBone does come with a pretty decent mapping tool, GoogleMaps, which I have used a few times with other people's iBones, so I am puzzled as to why people would feel the need to go out and download this rather limited version of the TomTom experience. Surely the vanilla GoogleMaps app gives just as good a service, and even has some bonuses in location pics and satellite imagery? Or is it that TomTom and Apple are banking on the average iBoner having more maony than sense?
