Why need phone on trip
From the article it sounds as if the thing needs a constant connection to your phone, which in turn needs a constant connection to the internet.
Surely they could put some memory and processing chips in the thing and make it work offline. This would save battery on the phone but also save money on internet costs, make the thing work in areas with poor phone reception, and even dare I say it allow for more privacy.
As it is it's a nice accessory for a phone, not a thing unto itself. About as keen as a music-streaming app as compared with an iPod.
