If the SE2 does not retain the physical home button and a headphone jack, then it is no longer a "SE". It is SUPPOSED to be a cheaper "retro" design. I know a lot of you can't understand it, but some us actually consider the SE to not only the perfect size, but a classic "perfect"design. Not everyone wants a "phablet".
Besides all you bleeding edge techies already have a LOT of options, let those of us who like this form factor have this one phone.
