Win 8

Microsoft are trying (and failing) to revolutionise the PC market with Windows 8 and their Surface tablet.

 The problem is that Windows 8 is a confused product: it tries to squeeze both a tablet operating system and a desktop operating system into the same package.

 This means that there are two incompatible user interfaces: the touch screen interface designed for tablet users and the desktop interface, which is similar to that in previous Windows versions but crucially lacks the Start menu.

 However, it seems that it is not just Microsoft that has been confused by their new operating system as PC manufacturers struggle to build devices that take advantage of the two distinct interfaces.
