Imagine sitting down at your computer. It recognizes you as an authorized user—conveniently, without a complicated password. Then you embark on a test flight and wonder in the middle of it what the altitude record of the SR-71 is. Your digital assistant knows the answer. Speaking of records, of course, your notebook starts (almost) as fast as The Flash and is particularly slim. Sounds like a comic book hero? Not at all. All you need for this is a modern notebook or convertible with Windows 10.
