Does this mean I can turn my next computer on and use it right away?
Does this mean my phone that takes 40 seconds to boot will be usable right away just like the first cell phone I had years ago?
In theory, yes. In reality, by the time these reach the consumer market, Windows 15 will be the most common operating system, requiring 1.21 petabytes of memory (2.0 petabytes recommended), so Windows will STILL take 40 seconds to boot.
