Buy for Better Siri
Siri is better on the Apple Watch Series 3 in one major way. Now Siri can talk to you from the Apple Watch.
There is a faster processor that should help apps run faster and smoother, and this also allows Siri to speak to you on the Apple Watch 3.
On all the previous models you could talk to Siri, but you could not listen to any responses. This meant you would need to stop what you are doing and look at the watch for a response. if you are walking or running, this can take you out of your rhythm.
Users who upgrade can see this benefit on the Apple Watch Series 3 with GPS and the model with GPS and LTE.
