Microsoft isn't just content to work on a universal Skype app -- it has much bigger plans in store. It's developing a version of Skype for HoloLens that, as you'd expect, lets you chat and collaborate with friends using the augmented reality headset. Its exact functionality isn't clear yet, but the allure is clear: you can hold a hands-free video chat while you're walking around the room. Needless to say, that's helpful if you're working on a group project or have your hands full with other tasks. Don't worry if you can't drop $3,000 on a HoloLens unit to try it out, though, as there's plenty coming for regular users.
