I got my S3 LTE one day after launch, but I still use my S0 as a dedicated fitness watch. The battery life was getting atrocious using it as an all-day watch PLUS a workout, but now I have the best of both worlds: a silver S3 LTE with a milanese band that lasts all day (76% @ 12 hours!) and a space black S0 with a sport band for my workouts. By the way , a 1-hour 15-minute workout uses 54% of the S0 battery....crazy!
