So true also for me! It was a great surprise when the SE was announced, can't remember any rumors before....I bought the original SE because I hated the 6 design and was going to hold onto my 5s until it died. The surprise announcement of the 6s chipset in the superior design and smaller form factor sold me on it.
it was small with the good 6s camera (and no camera bump!), fast and beautiful. Still using it!!!
I would still buy a new SE with with new internals, better camera and the original SE design again in a heartbeat!
I am planning to update to a 12/13 mini - but I am in no hurry....maybe next 1 or 2 years, or a good second hand possibility pops up. Or the 12/13 mini gets at some point the next SE, but I expect not very soon - as SE 2025 maybe.
But the ultimate perfect thinkable iphone for me would still be the 4/4s size/design with a bezel-less 4 inch screen....
