In case you haven't noticed, Lenovo is showing off an insane amount of stuff here at CES 2015. Tablets, smartphones, a smartwatch, laptops, more laptops. Now, rounding out the list, we're seeing the company's latest desktops. Of the three, there's only one you probably want to know about, and that's the B50, a 23.8-inch all-in-one with Intel's RealSense motion-sensing 3D camera setup (as pictured in the above close-up). As it happens, you're going to be seeing RealSense on a lot of gadgets this week at CES -- everything from laptops to tablets to desktops like this. Depending on the form factor -- and also the specific company -- the use cases for that 3D camera are going to differ a little bit each time. After all, there's no accounting for what software they pre-load on the machine. In the case of the B50, though, Lenovo seems to be pushing the gaming angle -- in a demo, I played a game where I lifted soldiers to safety using an onscreen hand (operated by my real hand, of course).
