Totally agree. Small body is appealing. Update the tech, keep it small. I’d be willing to forgo touch and Face ID, just to use passcode if necessary. Remove the headphone jack, increase battery life, update camera so it’s stabilized with gyroscope.
Not realistic, but I would also love an e-Ink or Mirasol display option, so that battery life would last much longer. The tech has gotten a lot better, and readability in sunlight is fantastic.
