I see why they do it: I bought an apple watch 0 figuring I'd get an idea of what the fuss was about and then buy v3 when they got it figured out. Instead, within the first week, I turned around on my way to work because I hadn't put my watch on.
OTOH I got an M1 ipad pro when it launched and ended up returning it and getting an air which was just as good for my needs. As it happens the pro had some hardware bugs anyway but if I'd liked it I would have just asked them to swap it.
