iPhone X
The big story with the iPhone X is the Super Retina Display. It's 5.8-inches on the diagonal and has 458 pixels per inch. It's the first OLED display for an Apple phone and for some reason it has rounded corners. It will, in fact, start at $999, which has already been a hot topic in blog posts.
Phil talks about how OLED has color accuracy issues, which has been true in the past, but has been worked out for a while. He also talked about True Tone, which intentinoally changes the color on your screen to fit the surroundings. It has HDR including Dolby Vision, so this screen is probably a lot nicer than your TV. Despite the fancy screen, it gets two more hours of battery life than the iPhone 7.
There's no more room for a button. THERE IS ONLY ROOM FOR SCREEN. So, now you swipe up from the bottom to go to the home screen. The same bottom-up swipe also enables multi-tasking and switching between apps. The larger side button will also now summon Siri if you don't want to call her with your voice.
