I've had a few SE's, and they have been fine, but:
It has always annoyed me that even though it has a larger case, the screen size is reduced considerably due to the massive top and bottom bezels. I've been very happy with the 13 Mini, and the expected size of a new SE puts it out of the running for me, even if it has a full screen. The lower cost of an SE is a non issue for me. The battery on my mini is starting to go, and my only hope is Apple won't screw up my phone during the replacement.
