kinda wish for a device similar in size /shape/ design to seventh-generation iPod nano today with
watchOS10 / iOS17 or a hybrid of watchOS and iOS (although able to exist on it's own without iphone - and actually, this type of device, a sort of ipod nano that runs watchOS on a 3.5 inch widescreen for like $300 could help pave the way for future "regular" watchOS innovations, so that, it could serve as a testbed for things like independent apps and services running right from watchOS.
8gb ram
WiFi6 (or wifi5 if that's more realistic for the size)
128gb / 256gb storage
dual camera (or single camera if that's more realistic for the size
A17 processor (or A16 if that's more realistic for the size)
4000mah battery (or 3000mah if that's more realistic for the size)
what else
maybe essentially an iphone 16 mini. they could do an iphone 16 mini right and just make like 5000 (or 10,000) of them, sell out, and make 5000 (or 10,000) at a time. that way they wouldn't have to feel like their producing too many. just make them in small quantities until they sell out, then only make more once they've sold out. they could do mini's every three years. so the 16 mini would exist until the 19 mini comes out. would help to fill that niche of folks who want the mini without having to like, even advertise it or whatever. just sell it to the niche of people who want it.
