I appreciate any update to the SE, but I agree the rumored specs are not very compelling. The A10 and the FaceTime camera are really the only improvements. The FaceTime camera is pretty minor to me, and how much better is the A10 than the no-slouch A9? And the battery might be a little bigger, but that doesn't necessarily mean better battery life, depending on other changes.
This update would be great for anyone jumping onto the SE from another phone, or an existing SE owner who REALLY wants a better face time camera, but for the remaining SE owners, it's not much of an upgrade to look forward to. Maybe in a year or two when the A9 starts to slow down, some may be looking for any speed improvement they can get, but by then I'd imagine the next update would be right around the corner.
Personally I would have additionally loved any of the following: storage increase, improved back camera, waterproofing, inductive charging, fast charging, 3D Touch, and display and speaker improvements. Ram increase and true tone would have been good too. I would upgrade from my current SE with the addition of one or two of those.
Hopefully the rumors are incomplete.
