Apple Watch shopping is proving to be fun.

Series 3's are way down in price, but the extra benefits of the series 4 make sense for me. Do I spend 1/4 the price on an older watch thats good enough or do I spend more for a fully featured device!

I don't see longevity as an issue, as I need nothing more than for it to connect to my phone and work as a smart watch. I don't see this failing in the foreseeable duration of the device, so it's all about price versus value.
