There is no point in being disappointed about the SE. For some people, it will be perfect. Me for one. I may still wait to see what the 7 comes out as but for me, it's a 4/5 style phone with a superb camera and all the bits and functionality I need. I personally don't much like these slither type phones like the one I have now. I liked my 4S more than any other phone I've had. Solid and useful. The fact I can get that again but with LTE, VoLTE , Apple pay, wifi calling etc. etc. and an even better camera is a winner. The screen is not really the most important part for me as I struggle to use even my ZTE slab for anything serious. Always end up on the iPad or PC for browsing. That's just me but it will also be a lot of other people.
I work most of the time outside with the phone in my pocket. These big, flat slabs are never comfortable in that environment. I very much like it and I think I might get one. I think it will be a winner. Updates a classic design that many are comfortable with and adds in all the new power features we are going to need.
