Okay, so I am thinking of upgrading from my launch (series 0?) AW to the series 3. Will I notice a significant difference in the speed of apps being launched, etc? Also, I like the Nike sports band, but don’t care for the Nike+ ecosystem (Strava user here). Can I just buy the Nike+ edition and use a different watch face? What are the main difffernces in the UIn can the Nike version function the same as the standard edition? Cheers, Andy.
