After surprising us with the Surface Book last year, what could Microsoft have in store next for its flagship PC lineup? We'll find out today during its Surface media event in NYC. As we explained in our preview, rumors currently point to an all-in-one PC that can be converted into a large tablet. It could be something like a cross between the iMac and the Surface Hub. We might also catch a glimpse at Microsoft's Amazon Echo and Google Home competitor, the "Home Hub," and hear more about how Windows 10 will evolve. Microsoft's Surface event will kick off at 10 am Eastern. Check back here for our live coverage as things kick off.
