Sometimes, putting some gimmicky features to an already working machine would just mess things up. And that's what is happening to Microsoft's Windows 8 touchscreen computers. 

According to Computerworld, research firm IDC has reported that it will reduce its previous prediction on touch PC shipments from 17 to 18 percent to between 10 and 15 percent. IDC analyst Bob O'Donell says that the key reason for the failure of Windows 8 touchscreen computers in sales is its hefty pricetag. 

"They're generally in the $699 to $799 range", he said. "They're generally in the $699 to $799 range," he explained. "That's hundreds more, sometimes as much as double the price, of non-touch notebooks." 

O'Donell also said another reason why touchscreen computers did not generate the predicted sales is because it is seen as unnecessary by most PC users. With all the gadgets currently available in the market, including touch phones and tablets, consumers would not want to have another touch-powered device when they are already satisfied with the tradional keyboard and mouse of the PCs. 

With all these obstacles Microsoft is facing, O'Donell says that its biggest hurdle is to make Windows 8 run gloriously in a non-touch computer. 

"90% of the PCs sold this year are not going to have touch", he added.
