Series 2 with its ceramic back is it worth picking up a used one over choosing the new series 3 wifi model?
Added a barometer as well.So outside of being able to make calls from your watch, there's very little to gain by going to 3 from 2.
BT and WiFi are faster and cpu is faster so everything is smoother and faster.I'm also wondering what needs to be FASTER? The series 2 on OS3+ transitions are pretty quick and don't really need to be faster. maybe they upped the processor in order to enable live Siri
