Thanks. I can only find refurbished series 8 and also refurbished series 9 with the smaller screen for almost the same price. Will the 9 be more future proof in terms of support? I don’t plan to be upgrading it and would like it to remain useful as long as possible.
when will new models be coming out?
It's anyone's guess when new models are coming out. But, in the past, Apple has refreshed the Watch line in the fall (September/October), I believe. So unless things change this year, and they very well might, then a refresh might come in the fall.
I'd imagine the Series 8 and 9 will be supported equally as long, but I'd always recommend going with the newer model if I could swing it, price-wise.
Screen size is of course personal preference, but I prefer the 45mm (or 49mm Ultra) over the 41mm. I find it easier to interact with (text and buttons are a bit larger) and the battery life is generally a little better as well. My wife has a 41mm and she's more than happy with it.
My wife mainly uses hers to track her fitness/workouts/calories, but enjoys being able to read & respond to text messages without having to track down her phone. She doesn't use it for any third party apps and such.
I, on the other hand, use mine for everything -- tracking fitness/workouts, notifications, calendar & next coming appointments, messaging, work & personal email, controlling the AppleTVs, controlling smart home devices, remote control of my vehicles (Tesla and Volvo)... you name it. I consider myself a watch power-user and I'm really enjoying the Ultra 2.
