I'd say this. If you're upgrading from an air/air 2 or the 2017 ipad, i'd say get the air 3. because it would likely last you until 2023/2024. I got the air 2 in oct 2014 and kept it until the 2018 pro. I'm not getting rid of it until it breaks.
these days, you pay more for what apple offers with less innovation (which is BS). but there isn't much more innovation available that won't drastically increase the price.
i had my laptop for 5 years and it ended up actually having to get a replaced battery and also had some security holes and didn't perform as fast, but it was definitely something i could've kept for another year or so. the last 2 things for me to upgrade are the watch and my phone (probably next year for both).
