One of my friends has argued that tablets will one day replace desktop (and laptop) computing. His main argument is that there's a trend away from desktop computing to tablet computing and that sales for tablets are growing and soon surpassing desktop computers.
I disagree, and tend to think the desktop/laptop computer will be around for a long time because of the ergonomic infeasibility of using a tablet for more then a few hours at a time, let alone a full work week. Furthermore the smaller screen size resulting in less productivity, and the weakness of a virtual keyboard compared to a physical one.
Is there research to support one view over the other?
