I've been waiting for a foldable iPhone for a couple of years now. I'm currently not satisfied with the software quality of iOS 18 (and to an extent watchOS 11) so if that doesn't improve I might look at other brands anyway, but if it improves this is the phone I'd get.
For me it'd likely completely replace my iPad, so I'm fine with it costing roughly what an iPhone Pro + iPad Pro cost. Some people here argue that one could just buy an iPhone and an iPad, but having a pocketable device that acts as both (to an extent) means I only have to worry about one less device for charging, carrying with me, updating, having two SIM cards, syncing etc.
I just hope they use somewhat state of the art hardware from the get go, I wouldn't put it past Apple to limit the outside display to 60 Hz for example just so they can make it 120 Hz for the second generation.
