Apple has been grabbing all the innovation headlines with the iPhone and the iPad and its iMac business has benefitted in the process. Microsoft showed off Windows 8 at D9 today and in so doing showed the world that markets are always open to those who innovate. Windows 8 has a completely different look and feel to the current operating system. Gone is the start button and the icons for apps. Instead the new version will use live tiles. These will be familiar to those who use a current generation of Windows phone. Indeed this is part of what makes Windows 8 so clever. It shares the same interface across mobile and PC, meaning you learn one way to find and access content. It also makes it easier to share content between systems. To get a good feel for Windows 8 see the demo on YouTube. Windows 8 looks very cool and may well be the kind of innovation that will draw Mac users back to the Windows platform. It also demonstrates why Nokia may have chosen to go the Windows route for its mobile products. I love it when you can actually see innovation and with Windows 8 that innovation is not just visible it’s also screaming at you.
