re: Windows 8 PC Makers Face Touch Trouble
Touch for desktops requires also a change in office furniture. The touch enabled monitors need to be mounted into the desktops at the correct angle and be large enough to accommodate a full size touch keyboard and provide enough screen space for applications. The best might be to have dual touch screen monitors plus a third touch monitor that is sized properly for a soft keyboard. Ideally, that special screen also provides tactile feedback as a real keyboard does.
So ideally we'd need special touch enabled monitors (and throw out all the fully functioning monitors we have now) and have to buy all new office furniture with the proper mounts (and throw away all the desks we use now) just to use the "Modern UI" efficiently on a desktop system. The cost for a W8 license would be totally negligible in this scenario as are the training costs and productivity losses until users get accustomed to the new setup. Now, why again is a touch optimized UI that cannot be turned off easily offered as in your face change with W8? Am I missing the point?
