The Desktop has been relegated to just another app to run in the Metro. And it’s underpowered compared to earlier versions of Windows–start orb, Start menu and Quick Launch toolbar is now nowhere to be found. Given that the app that most people use in their everyday lives–Microsoft Office–it will only run on the Desktop, it means that Windows 8 for many people would be less useful than previous versions of Windows.
Why is Microsoft doing this? It lost the battle of the t and smartphone Android and iOS, and Windows 8 t will power and finally a Smartphone. Microsoft hopes that people will want one interface on all their devices, Windows 8 interface.
That was a mistake, because the desktop is not t or smartphone, and require a different interface. Apple admits it, and so when it designed the iOS, it is not repeating the Mac OS x. Cisco iOS based on Mac OS X, and they share a common foundation so that the Mac OS X and iOS device can work smoothly with one another and share information and data, as in iCloud.
