Well, this is new: Lenovo and Motorola have had US launches before, but this year they've basically transplanted their entire Tech World event right into the heart of San Francisco. The festivities (if that's the right word) will begin at 10AM Pacific/1PM Eastern and we'll be covering all the day's news as it breaks, so stay tuned. Expect to get your first look at Lenovo's first Project Tango phone very shortly, and if we're lucky, maybe Motorola's new flagship phone will finally break cover too. Not a bad way to spend a Thurday morning/early afternoon, right?
