Acer is showing up at CES with a lot of laptop upgrades in store, and its Windows PC revamps have a few tricks up their sleeve. By far the highlight of the mix is a new version of the high-end V 17 Nitro (above) that includes an Intel RealSense 3D camera. The depth sensor lets you control games and other supporting apps with hand motions instead of reaching for the trackpad and keyboard. If you're the creative sort, it'll also let you scan your face and other 3D objects for inclusion in games or 3D printing projects. There aren't any major upgrades under the hood, although you're still getting a beefy 17-inch desktop replacement between the quad-core 2.5GHz Core i7 chip, GeForce GTX 860M graphics and choice of solid-state (128GB or 256GB) or spinning hard drive (1TB) storage. You won't have to wait long to give this system a try, as it's shipping in January. However, it's not yet clear what the trick camera adds to the price, if anything.
