PlayStation 4's UI and inner workings detailed: No more booting, games download as you play them

We've heard some hardware numbers, but now we're hearing more how the PlayStation 4 will actually work in practice. Alongside connections to other Sony hardware, the highlight that caught our attention was that you'll be able to leap back into your game by pressing the power button. From off. Better still, there's also a secondary custom chip for uploads and download and with that, the PS4 will let you play your new titles as you download them. The rest of the game will continue to be piped into that ample hard drive. You can also share (with that new button) 10 seconds of video, trimming and uploading your own gaming highlights to your buddies -- heck, you can even stream it, with allies 'tagging' in and taking over the controller.

In fact Sony will make social networks far more integrated, with "real people", photos and companion mobile apps to augment this. You'll even be able to browse video remotely from the likes of your smartphone, tablet or Vita. The system itself will also learn your preferences and download content it reckons you'll like. Personalization is shaping up to be a big focus for Sony.
