Microsoft believes that the next version of Windows is such a big upgrade over Windows 8.1, that the company skipped Windows 9 and gave it the name Windows 10 in one go. Joe Belfiore calls Windows 10 the "most comprehensive platform ever." They have us excited with that. "We want all these Windows 7 users to have the sentiment that yesterday they were driving a first-generation Prius, and now with Windows 10 it's like a Tesla."
Terry Myerson of Microsoft said "Windows 10 will deliver the right experience on the right device at the right time," and that "Windows 10 will run on the broadest types of devices ever." A unique interface will greet you depending on the type of device on which you are running Windows 10.
You can think of Windows 10 as the best of Windows 7 and Windows 8, thrown together into one cohesive package. The new Start Menu combines the traditional Start from Windows 7 with the Metro home from Windows 8. Live tiles are still present, and will continue to be useful.
Windows 10 will feature superior multi-tasking; users will be able to snap four apps side-by-side on the screen. Seamless multi-tasking is the aim, and it looks like Microsoft just might nail it this time.
Windows 10 will run across an incredibly broad set of devices - from the Internet of Things, to servers in enterprise datacenters worldwide. Some of these devices have 4 inch screens - some have 80 inch screens - and some don't have screens at all. Some of these devices you hold in your hand, others are ten feet away. Some of these devices you primarily use touch/pen, others mouse/keyboard, others controller/gesture - and some devices can switch between input types.
Microsoft doesn't want to abandon PC users with a mouse and keyboard. At the same time, Windows 10 will be touch-optimized. The right experience on the right device? We hope Microsoft delivers on these big promises.
A new "Continuum mode" will make the transition between tablet and laptop modes in devices such as the Lenovo Yoga Pro 2 a more seamless experience. "We want to support those Windows 8 users who have touch machines and getting a lot of benefit out of them," said Belfiore. "What you get is a device that operates with the simplicity of a tablet, but morphs itself back to the familiar PC experience."
Windows 10 "Insider Program" will launch tomorrow. The final version of the OS is expected to arrive at BUILD 2015.
