1/ this dock argument doen't make any sense whatsoever.
2/ when I hold my 7+ in landscape mode I never put any finger on the front side, as it should be.
3/ nope I don't think that's what Apple had in mind, "make sure it doesn't look like a Samsung or an LG"...
...what I think they had in mind though, is that YOU HAVE TO PUT THIS SPEAKER, INFRARED CAMERA, SENSORS, ETC, SOMEWHERE!!!!!!
Have you guys even noticed that the S8 or LG are not really edge-to-edge? Why, because they have to put the same stuff as Apple on the FRONT. I hate to break it to you but the iPhone X is STILL A PHONE. Maybe you'd rather have the speaker on the back so everyone could complain how dumb Apple was to not have it *on your ear*.
Maybe that will change, maybe technology will allow them to do things differently in the future, but for now, that's how it is. It's not a home theater, it's not a photo album, it's A PHONE. Get over it FFS.
