No idea, sorry. I want to say, they're all just adding more cameras and not much else. BUT... software updates end eventually so keeping for 10 years isn't a great idea. My guess, pay to have a new battery put in, and it'll be good for a few more years, then upgrade when that battery gives up. Cheapest path.My (youngest) daughter just yesterday got a 17e. What are a few top differences from a standard 14 => 17/18?
I ask this way because my 14 battery is struggling a bit. New battery or 17e or ??
