my SE 64GB is nearing the end of it’s useful life (battery is old, dust on the front and main camera, broken back glass ). I’m looking into either a second hand 128GB SE or getting an out of warranty repair. The small size and one handedness are just essential features in so many situations. i really wish they made an updated SE with a full screen front and updated cameras. And the real black aluminium back. from the iphone 5.
