Microsoft's message is strong. Windows 10 will be used by more than a billion people by the time these babies (the next generation) are 10 years old and they will grow up in a Windows 10 world where passwords aren't needed, a world where you can scribble on your webpage and share with friends, they will grow up in a world of Windows 10 and Cortana as a personal digital assistant, who knows everything about them.
It's a really powerful message, it envisions what the furture will be like for the next generation and a video clip with babies perfectly delivers that message.
Windows 10 will be available on July 29th as a free upgrade to Windows 7 and 8.1 users.
