So in looking at the comparisons on apple's site... Series 2 gets GPS and swim proofing. All the other stuff (i.e. the new workout apps, apps in dock, etc...) we get via WatchOS3... right? So I'm wondering (other than apps loading faster) why I need a new one? I don't run, walk or bike without my phone... Most all of my workouts are done in our home gym... so I kinda don't care about GPS, unless I'm missing something.... I get all the other niceties with OS3... I do think my apps load REALLY SLOW... battery life is the same (as in bad) Am I missing something?
