Own a PlayStation 4? Today's your day: the console's big 2.0 update is finally live. Sony's been teasing the update for weeks, lauding the console's new ability to play music from a USB drive, the availability of system menu themes and promising new voice commands, party options and a less crowded home-screen. The update also gives the console's unique "share" button a little more power: the ability to upload video clips directly to YouTube and, most notably, remotely stream your games to a friend over the internet. Sony invited me to try some of these features ahead of today's launch and, yes, they all seem to work just fine -- at least in a controlled environment.
