Microsoft initially blamed the modest sales of Windows 8 on the lack of hardware;
"Frankly, the supply was too short," said Tami Reller, at the time the CFO of the Windows division, in January. "I mean, there was more demand than there was supply in the types of devices that our customers had the most demand for."
So they made the hardware available and people still did not want it.
I was among them who thought that combining a laptop with touchscreen was a good idea; since a tablet is to big for a phone and to small for a computer.
But then again; people do not really need the touch screen if the keyboard and the mouse are in place.
And they certainly do not want to pay a double price for it.
Another reason could very well be that PC's with Windows 8 are restricted hardware and thus faulty by design.
Pay more for something that has less functionality - that simply does not compute.....
