Re headphone jack. Eve could engineer and produce a usb-C plug headset I imagine. Couldn’t be that hard. Small, 90° angle. Could market that beyond just Eve.
Writing this from a Note 8, by far best phone I’ve ever owned. For Eve phone, would need killer specs, stylus, great screen, LOT of memory. Top Eve version should be to, say, a Note 8 what top end V is to Surface Pro
Imo the niche that is open it’s high end Enterprise, niche the Surface phone meant to fill.
Ps - can’t wait to get my Eve!!!
