This is why I think Microsoft's tablet strategy with Windows 8, one OS to handle both mouse based and finger based input, is flawed and that Microsoft doesn't really "get" touch.
In case you've been kept out of the loop, Microsoft introduced a new keyboard and mouse that are designed to work well with tablets. Arguably the keyboard is a useful addition. Typing on a touch screen simply is not as efficient as the traditional physical keyboard. But the very need to create and market a mouse for a device designed to accept finger touch input is a sign of a flawed strategy.
You see, if you could perform your most basic tasks completely using touch then this isn't nearly that big a deal. But, when Windows 8 dumps you into a desktop interface for various routine tasks then there's an issue. The "tablet mouse" is being marketed because, at least for the initial release, you will need a mouse input to, at the very least, setup your new Windows 8 "tablet".
This is completely ignoring the fact that the majority of Microsoft's powerhouse applications, think Office, aren't touch friendly...at all. These faults boil down to the very basic level, Windows is designed for a desktop, not a tablet. The two mediums are different enough that they warrant different approaches. Microsoft has refused to recognize this and still believes that a desktop/tablet experience can be shoehorned into the same device.
If Microsoft had been able to compete with this strategy from day one of the touch revolution it might have worked. But, 5 years from the launch of the iPhone people have expectations for how touch devices should operate. 3 years of the iPad means that they know how a tablet specific OS is supposed to operate. Your average user is not going to put up with being dumped into drastically different interfaces, one of which doesn't support the primary method of input for the device, anytime you try to do something on the tablet that isn't touch-ready.
This boils down to one thing: Microsoft's refusal, or inability, to truly separate the desktop and tablet OS the way they should be.
