I think you are asking the wrong people. Those that hang out on this forum are pretty techy people so will heavily favor desktops or both.
I think less techy people ("average" computer users) are using desktops less and most, if not all, of their computing needs can be accomplished using a tablet. These people mostly surf the web, use social networking sites, email, stream video, etc... which can all be done using a tablet.
