As you probably know, Google will host a press event in less than an hour in San Francisco, where the Mountain View-based company is expected to introduce Android 4.3 Jelly Bean and the next-gen Nexus 7 tablet. The Android 4.3 Jelly Bean launch event will be hosted by Sundar Pichai, head of Android and Chrome, but most important it will be streamed live on YouTube so all of you can watch it.
