The interface is fairly straightforward, with options to manage contacts, check your messages, listen to music, and track your workout. The four buttons surrounding the device will also help you get around.
Battery life could prove problematic: with the GPS and cellular radios turned on, it's estimated at 8 hours. Play music, and that drops to 4 hours. If you're just using cellular data, however, you can expect the watch to last approximately three days.
