Would agree that it's not a good idea - for all the reasons above and more.. Agree it's good for tablets and smartphones but not for computers. Touch-screen may be here to stay, but there will also be technologies to replace and out-date it too.
In terms of personal computers having had their day, it simply isn't true. What is happening is an ever-widening proliferation of available technology and an ever-widening amount of varied technology in homes.
For example the people I work with have technology varying from tapes to mp3; from diskettes to SSD; from downloads to physical CDs and DVDs; from 15" CRT monitored Windows XP computers through the latest smartphones and flatscreen iMacs. Some people have all of the above and many variations of the above. The more technology advances, the more varied the technology that people own!
